Microsoft Ergonomic Keyboard

I have a Microsoft Ergonomic Keyboard but I cannot choose it in Manjaro 21. It’s possible to choose Microsoft Ergonomic Keyboard 4000 but it’s different from Microsoft Ergonomic Keyboard. The keyboard works but I cannot use all keys.

Microsoft Ergonomic Keyboard have the keys from the left
Ctrl, Menu, Windows, Alt, Space, AltGr, Office, Emoji, Ctrl
(I think that the second key is named Menu. When I click it I get a menu with the first line “paste”).

How can I use all keys on the Microsoft Ergonomic Keyboard? The Office and Emoji keys is made for Windows so I want some other functionality in Linux. I have already changed AltGr to Alt R.
