How do I use the OAUTH 2.0 API?

I am a clinical researcher. We are using the Garmin Fenix 7S in a distributed study to extract data from our study participants. We would like to use the REST api, but we are having a difficult time understanding how to register and use the Garmin REST API.

If you have joined the Garmin Connect Developer Program, you will have access to the Garmin Connect API which uses OAUTH1.0 , not OAUTH2.0, and they advise they have no plans to implement 2.0.
