O-auth endpoint

Hi everyone, I am trying to have a third party app connect to my Bubble app. The goal is to have them authorize my users and create users on their app that corresponds to my users.

I am having trouble identifying my o-auth endpoint. Does anyone know how to find this? Is it in a backend workflow? Or, do I need to create a backend workflow?

If helpful at all, I am attaching a screenshot of my backend workflows.

I used Canvas to create my app, so some of the backend workflows you are seeing were created by Canvas.

Thanks!
Bryan
