It's simply the statement I listed in my post. There are no variables, I just wrote it like that to not post the exact values. So it's something like this in the script and that's it:

ls file:/Workspace/Repos/my_user_name@company.com/my_repo_name/my_folder_name

By the way I'm on Azure Databricks. Sometimes it seems this variant doesn't support all the features the AWS/GCP variants do.
