Using a filter for translation and Polylang

Thank you very much for your great plugin. I usually use the “essential_form_settings” filter for text. Now, I had to configure it on a multilingual site. Would you approve this approach? It seems to work perfectly fine. I just want to make sure that I’m not missing anything:

add_filter('essential_form_settings', function($options) { // NOSONAR
    $email = 'kontakt@example.com';
    $lang = function_exists('pll_current_language')
        ? pll_current_language()
        : 'de';
    $translations = [
        'de' => [
            'email_from' =>  $email,
            'email_to' =>  $email,
            'email_subject' => 'Eine Nachricht aus dem Kontaktformular',
            'label_name' => 'Name',
            'label_email' => 'E-Mail',
            'label_message' => 'Nachricht',
            'button_text' => 'Abschicken',
            'agreement_text' => 'Ich stimme den Bestimmungen zum Datenschutz zu.',
            'success_message' => 'Die Nachricht wurde gesendet. Vielen Dank!',
            'name_missing_error' => 'Bitte das Pflichtfeld NAME ausfüllen!',
            'email_missing_error' => 'Bitte das Pflichtfeld EMAIL ausfüllen!',
            'email_not_valid_error' => 'Die E-Mail scheint nicht korrekt zu sein.',
            'message_missing_error' => 'Bitte das Pflichtfeld NACHRICHT ausfüllen!',
            'message_too_long_error' => 'Die Nachricht ist zu lang. Bitte nicht mehr als 50.000 Zeichen!',
            'missing_agreement_error' => 'Bitte den Bestimmungen zum Datenschutz zustimmen.'
        ],
        'en' => [
            'email_from' =>  $email,
            'email_to' =>  $email,
            'email_subject' => 'A message from the contact form',
            'label_name' => 'Name',
            'label_email' => 'Email',
            'label_message' => 'Message',
            'button_text' => 'Send',
            'agreement_text' => 'I agree to the privacy policy.',
            'success_message' => 'Your message has been sent. Thank you!',
            'name_missing_error' => 'Please fill in the required NAME field!',
            'email_missing_error' => 'Please fill in the required EMAIL field!',
            'email_not_valid_error' => 'The email address appears to be invalid.',
            'message_missing_error' => 'Please fill in the required MESSAGE field!',
            'message_too_long_error' => 'Your message is too long. Maximum 50,000 characters!',
            'missing_agreement_error' => 'Please agree to the privacy policy.'
        ],
        'fr' => [
            'email_from' =>  $email,
            'email_to' =>  $email,
            'email_subject' => 'Un message du formulaire de contact',
            'label_name' => 'Nom',
            'label_email' => 'E-mail',
            'label_message' => 'Message',
            'button_text' => 'Envoyer',
            'agreement_text' => 'J’accepte la politique de confidentialité.',
            'success_message' => 'Votre message a été envoyé. Merci !',
            'name_missing_error' => 'Veuillez remplir le champ NOM !',
            'email_missing_error' => 'Veuillez remplir le champ EMAIL !',
            'email_not_valid_error' => 'L’adresse e-mail semble invalide.',
            'message_missing_error' => 'Veuillez remplir le champ MESSAGE !',
            'message_too_long_error' => 'Votre message est trop long. Maximum 50 000 caractères !',
            'missing_agreement_error' => 'Veuillez accepter la politique de confidentialité.'
        ],
    ];
    return $translations[$lang] ?? $translations['de'];
});

add_filter('essential_form_agreement_text', function($text) { // NOSONAR
    $lang = function_exists('pll_current_language')
        ? pll_current_language()
        : 'de';
    $pages = [
        'de' => '/datenschutz/',
        'en' => '/en/privacy-policy/',
        'fr' => '/fr/protection-des-donnees/',
    ];
    $texts = [
        'de' => 'Ich stimme den Bedingungen zum <a href="%s">Datenschutz</a> zu.',
        'en' => 'I agree to the <a href="%s">privacy policy</a>.',
        'fr' => 'J’accepte la <a href="%s">politique de confidentialité</a>.',
    ];
    $url = get_home_url() . ($pages[$lang] ?? $pages['de']);
    return sprintf(
        $texts[$lang] ?? $texts['de'],
        esc_url($url)
    );
});
