We plan to use the Google Identity Platform for an upcoming portal project. We want to build a few different React-based web clients for this project, and miscellaneous APIs. I don't see a way to add an additional Client to Identity Platform. My expectation is to be able to define a client, set it's individual permissions, etc, and get a Client ID and Client Secret (if not a public app). Where do I go manage this, please? I'm used to using IBM Security Verify where all of these options are available.
