Migrate to VS Code from Eclipse on Mac

I am starting by setting up a new project but it's not compiling and I'm getting errors from the compiler that I don't understand.

I suspect it's struggling with the space in the "Application Support" folder name in  /Users/{myUserName}/Library/Application Support/Garmin/ConnectIQ/Sdks/connectiq-sdk-mac-4.0.6-2021-10-06-af9b9d6e2

And also I have not found where I associate my Developer Key to the VS installation.

Could someone help me with this please?
