Postman OAuth 2.0 Authorization for SCIM

I am trying to call (via PATCH) to update user email addresses within Asana, however, I have no clue how to setup the OAuth 2.0 configuration for authentication, which is required for SCIM. I have my Client ID and Client Secret, but beyond that I’m not sure what else I need to provide in the settings.

This is what I have right now, but when I click ‘Get New Access Token’, it doesn’t authenticate.

Any help would be appreciated!

Thanks in advance!
