I’m totally new on GitHub, and don’t know how to make good use of it. How do l make use of this link https://docs.github.com/en/authentication/connecting-to-github-with-ssh/testing-your-ssh-connection?platform=windows ??
My purpose is to try out my SSH key.

Yeah, but I assume that given that he’s posting to linux4noobs, he’s trying to do this on Linux.
I use WSL.
Then, you’re effectively using Linux. The terminal emulator you should be using is the PowerShell in which you should start the the BASH provided by WSL by typing
wsl.
