Android Emulator

I installed OR in an emulated Android OS, which works fine, but I still have a problem.

When in chat the enter/return key doesn’t work. I can type in any character from my PC keyboard, but I cannot send the text to the chat. Nothing happens on enter.
I suppose this problem is specific to the programming language of Android, that doesn’t seem to recognize the enter-key as valid. I also switched to a soft keyboard, but in vain.

As emulator I used Andy OS and Nox. Both have the same problem.
Is there a possible workaround?
In Nox there is a built-in keymapper, but I can’t find the right command to assign the send text function to another keyboard key.

Found the solution myself.
Installed the Google Keyboard (GBoard) as default keyboard in the emulator and the problem was solved.
