I have tried using the following setup guides for the ATOR plugin:

https://medium.com/@kashwathkumar/authentication-token-obtain-and-replace-ator-burp-plugin-fast-and-reliable-plugin-to-handle-b19e3621c6a7
https://www.youtube.com/watch?v=h1p2rvooTL0&t=6s&ab_channel=ashwathkumar

Also tried various filters to see if it was an issue with the pattern in the setup process. Additionally, I have deduced that in the Logger for the plugin that the Token auth Request is being made successfully, but the new access_token is not dropping into the Request. I attempted to use a longer string to the left and right of the From Selection filter, but still no success. Any suggestions would be most appreciated.
