creditcard.php found in mu-plugins directory: Is it still needed?

Hello, I found a Forminator creditcard.php file in my site’s mu-plugins directory. Is this plugin still required or can I remove it? I’ll paste the code below. Thank you.

<?php
/**
 * Plugin Name: [Forminator Pro] Replace statement_descriptor
 * Description: Quick fix to replace statement_descriptor with 
 * Author URI: https://wpmudev.com
 * License: GPLv2 or later
 *
 * @package WordPress
 */

if ( ! defined( 'ABSPATH' ) ) {
	exit; // Exit if accessed directly.
}

add_action( 'plugins_loaded', 'replace_statement_descriptor_in_stripe_library' );

function replace_statement_descriptor_in_stripe_library() {

	// File containing the async request class.
	$file = WP_PLUGIN_DIR . '/forminator/library/fields/stripe.php';

	// Check if async request file exists.
	if ( ! file_exists( $file ) ) {
		return;
	}

	// Get the file contents.
	$content = file_get_contents( $file );

	// Check if we have content.
	if ( ! $content ) {
		return;
	}

	// Change statement_descriptor to statement_descriptor_suffix.
	$new_content = str_replace( "['statement_descriptor']", "['statement_descriptor_suffix']", $content );

	// Update only if content changed.
	if ( $new_content !== $content ) {
		file_put_contents( $file, $new_content );
	}

}
