Redirect user after login with SMS

I want to redirect user to https://www.domain.com/author/<username>/screen after they log in with SMS

I tried to edit the code in includes/functions.php with the following code

$current_user = wp_get_current_user();
if ( is_user_logged_in() ) {
$redirect = (‘https://www.domain.com/author/&#8217;.$current_user->user_login.’/screen’); }

but it does not work it redirects to “https://www.domain.com/author/screen&#8221; without the username part. can you help me with this
