Nova4 use vue3. Cannot just add a menu to make it work on nova4

[ronvanderheijden]

@anditsung The code is broken, this fix has nothing to do with vue3 or any other front-end parts.

[anditsung]

code is definitely broken but only fix the compatibility on nova4
without updating the frontend still cant be use on nova4

I've tested it and it's working properly. You aren't even using this menu feature, so I don't get your comment.
Anyway, You can close this pull-request. I'll be using the fork, which does the trick.
