How can I disable a UM user programatically?

Hello,

is it possible to set the status of a user profile programatically to inactive?

My following code does not work for some reason, I get no errors in the error.log

// Disable the account
um_fetch_user(sender_id);
um_update_profile(array(
‘ID’ => sender_id,
‘account_status’ => ‘inactive’,
));
