Here’s my configuration for testing the client credentials flow using the Chrome extension, Postman. You can actually configure the OAuth 2.0 Playground to use the Client Credentials flow. Just click on the “Wheely” icon on the top right to open the configuration menu and select the “Client Side” Flow.
What does Scope mean in OAuth?

In the token the permissions will be in a roles claim. Yes, you need to use api://web-api-client-credential-flow/.default for client credential flow.
When do you need a scope in OAuth?
