I want to hide the edit button for a user with a specific group in the javascript.

I tested it with this, but this is not working right:

	   users.call('has_group', ['test_module.group_first_manager']).done(function (is_employee) {
            	if (is_employee) {
                    this.$button.find('.o_form_button_edit').hide();
                }
                else {
                    this.$button.find('.o_form_button_edit').show();
                }
            });

I want to remove the edit button for users that are in the gropu = 'group_first_manager'

So have anyone an input for me to fix my problem?

Thank you
