Miletus App in WSL2/Debian

I compiled the code-editor - app from the WebCore-Miletus Demos and tried to run it under WSL2/Debian. Is there a white paper, that describes, which packets have to be installed to run a miletus-app under Linux? With some google-searches, i found the necessary packages, the code editor starts, but i see no menu and the shortcuts with Alt-key doesn't work.
How can i make the menu bar visible?
Or do i need to install some additional packages?


Normally just WebKitGTK:

sudo apt install libwebkit2gtk-4.0-dev

See here: Introduction - TMS WEB Core

We have a Ubuntu test machine, just tested the demo there and the menu bar is visible. Might be something with Debian then. Which exact version do you have?
