How to define addition reCaptcha actions via wpcf7_recaptcha_actions

Hi there, I’m wondering if someone can clarify how to use the wpcf7_recaptcha_actions filter? I’d like to potentially define some additional reCaptcha actions.

In the existing array we have for example 'homepage' => 'homepage'

Is it possible to define custom page ID (or slug)? If so would that be defined as the value or the key in the array?

Example:

function custom_wpcf7_recaptcha_actions( $array ){ 
    $array = [
                 'homepage' => 'homepage',
                 'contactform' => 'contactform',
                 '1234' => 'about-page'
             ];
    return $array
} 

add_filter('wpcf7_recaptcha_actions', 'custom_wpcf7_recaptcha_actions', 10, 1)
