Expected vs actual behavior

I would assume codepace ssh command would just work but it seems to expect a public key that doesn't exist. I'm not sure when or if that was supposed to be created previously as I only used gh to auth and then try to ssh (so I could use rsync)

I have a different key for github but it seems that doesn't seem configurable for codespace use.
