Followers vs BP Connections

Hi.
I love your plugin.

I have a question. Im trying to add some code so that only people who mutually follow each other can send Private Messages to each other to cut spam.

Looking thru the BP forum, I found the code to do that, but it only works for those using Buddypress’s “Friend connections”. Doesn’t work with Buddypress Follow plugin.

Here’s the code snippet :

add_filter( 'bp_get_send_message_button', function( $array ) {
    if ( friends_check_friendship( bp_loggedin_user_id(), bp_displayed_user_id() ) ) {
        return $array;
    } else {
        return '';
    }
} );

How can I use this with your Follow plugin.
Thank you in advance.

Im on the latest WP and BP versions.
