Web API access token issue for some tables

Hello,

I'm triggering the api "/api/data/v9.2/{table}/$count" for different tables and it works for many of them.

I'm using OAuth client credentials.

For some of them (e.g. gitorganizations), I'm getting:

 {"error":{"code":"0x80040216","message":"AccessToken not found. Please make sure plugin is registered as synchronous and not called with app credentials."}}

Do I need a different auth flow instead of client credentials? the problem is that my app is a non-interactive server app.

What options do I have?

Note that I'm using a developer environment without any plugins modifications/creations.

Why some tables work but others fail
The error you see: "AccessToken not found. Please make sure plugin is registered as synchronous and not called with app credentials." is a Data-verse security model issue. With OAuth client credentials (app user), you’re authenticating as an application user, not a human user. That means you only get access to entities/tables that support application users. Some tables (like account, contact, systemuser, etc.) allow this fine. But some "special" tables (e.g. gitorganizations, activity tables, mailbox tables, or those that rely on user-context plugins) cannot be accessed with client credentials, because internally they try to resolve a real user access token. Instead of client credentials, authenticate as a real licensed user.

Can you please provide instructions for user authentication? Also, my app is a server-app and it's not interactive, meaning I can't support 2FA.
