Description of the issue

In OEP Client Tutorial 04 the user must setup the OEP API token as env. variable on his/her system. This step is not clear if it was not setup before.

Steps to Reproduce

1. Use this tutorial: https://openenergyplatform.github.io/academy/tutorials/02_oep_client/04_client_cli_upload/#setup
2. Set: SET token=%OEP_API_TOKEN%
3. error

Ideas of solution

All tutorials should reference how to set the OEP API token.

Either always use:

1. token = environ.get("OEP_API_TOKEN") or getpass("Enter your OEP API token:")

Or 2. set the OEP_API_TOKEN env. variable.
