Hello Colin Kahler !

This is the part of our Rocket chat app manual:

To enable this module, chat server must be installed separately.
Enter the chat URL in this module settings.
Then OAuth login must be configured. Generate Key & Secret pair in OAuth2 Server module by pointing chat URL and desired name.
After Key & Secret pair is generated you need to enter them in Chat Administration > OAuth > UNA.

Also, you need to review those instructions from Alex T⚜️ :
