Twilio Auth windows enviro variables

I'm putting together some python code to move and then delete recordings from Twilio. There's plenty of documentation online to help with the script but the documentation says that I need to add the authorization code and token as a windows variable. The documentation shows how to get to the correct location to add these variables but does not show exactly what to enter, which location to enter it into or the exact format that it needs. I'm am new to all of this. On my Windows 10 machine - in the new variable window - it asks for 'variable name' and 'variable value'. I need to know exactly what I put in and the format it should be in. Any help would be appreciated. Thanks!

Most information to create this code was gathered from https://www.twilio.com/blog/2016/05/bulk-delete-your-twilio-recordings-with-python.html

# Create a lock to serialize console output

    # threads can mix up output in one line.
