Send Mail after Profile Update

Hello.

How could i send a mail to admin when a user updates the profile? Also includeing what has changed.

I was trying to use

function action_um_after_user_account_updated( $get_current_user_id ) { 
// make action magic happen here... 
};         
add_action( 'um_after_user_account_updated', 'action_um_after_user_account_updated', 10, 1 );

But this doesnt seem to be the right trigger.

Thank you in advance,
Lpion
