How to select runtime for function?

I tried to deploy with both cli@2.0.2 and manual zip file, since cli@3.0.0 was not ready. Both of them ask for runtime configuration. I am not sure how to specify it. I did saw a runtime option in functions/settings but there were no options.

TL;DR

There is a bug with a dropdown for selecting runtime in the appwrite GitHub repository. Several users are experiencing difficulties selecting a runtime for their functions. The suggested solution is to wait for a fix to be implemented.
