Directly assign the user to the folder using the 'databricks workspace access' command with the user email and folder path as parameters, bypassing group assignments for simplicity.

Create a new group with the necessary permissions for the folder, then use the 'databricks groups add-member' command to add the user to this group, ensuring scalable permission management.

Use the 'databricks workspace create-folder' command to create a new folder with the user already having access, though this does not address existing folders.

Mount the folder to the user's workspace using the 'databricks permissions mount' command, though this is typically used for external storage rather than internal workspace permissions.
