How to get GitHub working?

Can someone help me with GitHub in the configurator ?
Is there a guide that I can follow ?
I followed this guide:
But it only works in the SSH Server Terminals and this with the username and password.
When I want to do this in the configurator I get an error.
I do the following steps in the configurator:
Git Init
Git Commit
Git Push --> Error
Cmd(‘git’) failed due to: exit code(128)
cmdline: git push --porcelain origin
stderr: ‘fatal: could not read Username for ‘’: No such device or address’
If I want to do this in the Visual Studio Code on my laptop I get also an error.
Can someone help me with this ?
Kind regards,
