On-screen keyboard for reTerminal DM

Hi everyone,

I’ve installed the current Raspberry Pi OS (64-bit) as well as the official touchscreen drivers on my new reTerminal DM.

Now I’m looking for a usable on-screen keyboard. I’ve tried matchbox-keyboard, but it’s hardly usable in the default configuration. I’ve seen a picture of a nice on-screen keyboard on a reTerminal which seems to be part of the factory OS image:

Does anyone know if this on-screen keyboard is part of the factory OS images also for the reTerminal DM? If yes, where can I download the factory OS images?
