[Plugin: Polylang] Translating text from a plugin

Hi,

I am a bit of a wordpress beginner. I am using a plugin “ny-subscribe” to have a subscribe button for the users on my page. I have set up polylang to translate most of the strings but it doesnt translate the “subscribe” text posted to the page.

I did some fishing around in the php files in the plugin and found that the strings are stored in a file called ny-subscribe-functions.php and it looks like:

$admin_fields = array(
array(
'slug' => 'ny_subscribe_field_form_heading',
'type' => 'text',
'label' => __('Form Heading'),
'val' => __('Subscribe')
),
array(
'slug' => 'ny_subscribe_field_label',
'type' => 'text',
'label' => __('Submit Button text'),
'val' => __('Subscribe')
),
)


I have no idea how to add these strings to the polylang list. I tried using the pll_register_string inside of these php functions but it says that the function doesnt exist.

would appreciate any help.
