Change GeForce now keyboard layout?

Is there some way to set the keyboard layout on GFN in the browser, or at least use the system keyboard layout from Gnome?

According to the Arch Wiki, i should start Chromium with --disable-features=UserAgentClientHint` and spoof the UserAgent to Windows, but this doesn’t work anymore. There are no Keyboard area in the settings.

If I use GFN on Windows, the area for keyboard layout is working.

Or is there some way to copy the settings from windows via Cookies or any other storage method?
