Can’t add Viber as a header social icon

I’m trying to use one of the 3 custom social fields as a viber link field (viber://contact?number=+00000000000). However I’m getting an empty link as a result.

I tried to add the “viber” protocol in the kses but it didn’t do the trick.

// Allow viber protocol in links
add_filter('kses_allowed_protocols', static function ($protocols) {
    $protocols[] = 'viber';
    return $protocols;
});

It seems that the URL disappears somewhere between customizer and saving the option in the database, since I checked the database and the option is empty there. Does Kadence use some extra URL validation?
