Germanized Support

Hey there,

I am using this PHP code to add the following Germanized email templates:

add_filter( ‘viwec_accept_email_type’, function ($email_types) {
$email_types[] = ‘customer_guest_return_shipment_request’;
$email_types[] = ‘customer_return_shipment’;
return $email_types;
}, 2 );

But after adding this snippet I don’t find any options to edit the templates. Could you help me out here?
