Notice: Undefined index: menu_name

Hello,

The module works but there is a php error:

Notice: Undefined index: menu_name in menu_item_extras_theme_suggestions_menu_alter() (line 87 of /var/www/html/project/modules/contrib/menu_item_extras/menu_item_extras.module)

A check must be made on the 'menu_name' index of the array $variables.

I think its related to the menu__toolbar__admin .
