Can't add menu item in main menu on android

I can’t find information about adding menu items in android firefox main menu. Before I added it so:
function addMenuItem(window) {

menuID = window.NativeWindow.menu.add({

name: “Show Toast”,

callback: function(){

showToast(window);

}

});

}
But in jpm I have no object window. Is it possible to add menu item in jpm?

This documentation page explains what you can and can’t do with jpm on mobile.

Will unsuported modules be added in next versions of firefox jpm?

No, the work is currently focused on the new WebExtensions API. JPM/SDK add-ons should be migrated to it once it’s ready to use.
