BuddyPress.org

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 '';
    }
} );

I am using the above filter to hide private message button to non friends. It works but it also hides private message button to site admins and bbpress moderators. I want site admins and bbpress moderatos (bbp_moderator) could send and receive private messages even if they are not friend.

Any solution?
