How i can add menu in my game

help me pls, i wanna add menu in my game,but idk how i can do it

There are as many approaches to that as there are stars in the sky ... if I may say so :)

One would need to know in detail what kind of menu you are after.

I recommend to check existing projects in the explore section to find one that looks like what you are after and take inspiration from there.

Also check the tutorials, there is a simple example there:
