Bug: apply_filters

Hello, you have the bug in wp-content/plugins/stripe-payments/public/includes/class-shortcode-asp.php class (lines 713 and 738):
apply_filters(‘asp_button_output_before_custom_field’, $output, $data);
should be
$output = apply_filters(‘asp_button_output_before_custom_field’, $output, $data);

The same problem with apply_filters(‘asp_button_output_before_tos’, $output, $data);

Because of it, these filters don’t work. Do you have GitHub repository for this? I’d made pull request, but couldn’t find it.

Thanks for your work.
