Mobile Menu edit not available

hi! I’ve searched for days for the right answer to no avail. I’ve created a mobile menu with the Mobile Menu plugin, I was able to edit the menu one time and now it does not show up under customizer. It is not under editor>navigation either. I’m trying to edit my mobile menu, not navigation. It says “Menu-1” but I cannot find where to edit that from my wordpress dot com home.
