First: this mod does not contain the admin menu. If you wish and if you are using my version, you will see that the description is the solution to this:

Second: to solve this simple problem, it is simply by writing this command in the console or in an autoexec file: bind 0 "slot10"

And with that you can close the menu.

Thank you very much. The problem has been solved
