@ps-spark you're welcome. Is it actually still valid or did you encounter something which has changed since 2019? I'm asking, because I switched to PopOS in the meantime, so I don't know the status of this as PopOS does a lot out of box regarding this.
So in the end if not all is valid anymore, we should mention this in the comments here
