Activate Sketchup 2021

I have a classic license for Sketchup on a shared computer lab. When I activate the product under one users it does not activate for the other user. How can I activate this product for all users or machine based? I have tired this option here which doesn’t work.

Are there any command line options to activate this product with macOS?

Do the account names hold special characters (eg’@‘)?
If you set up an account with the Apple ID, MacOS deletes the @ in that homedirectory. If you mess with that (by adding the @ back again) the activation_info.txt file that should reside in the main Library/SketchUp 2021 folder doesn’t populate the license welcome screen.
