Give access to a specific backend menu for a specific role

Hello,

I’m trying to give access to my editors to a plugin menu (WP email users).
I figured out I needed to give the “manage_options” capability to the editor role (it gave me access to other menus I wanted to add too, so that’s fine), now under AAM > backend menu for editor, “WP Email Users” is in the list and not restricted but it is not displayed the wp backend menu.

What am I missing for this one ?

Thanks
