It appears you are mixing up Microsoft’s 2 different types of Oauth.

Administrator grants are associated with an “application” permission type (no specific user logs in)
Delegated permissions are associated with each specific user logging in through an application.

Delegated Type

If you have created a “system” user for “delegated” Oauth access, that user must be granted permission to access the specific files/folders. Then, if you.

“connect” your Microsoft Graph Security Oauth2 API Credentials item, using that “system” user
accept all the granted (delegated) permissions
the node functions should work without getting 401/403/etc.

Application Type

If you need to use the “application” type Oauth

Create a generic OAuth2 API credential type, set the Grant Type to Client Credentials
configure the Access Token URL, Client ID, etc.
There is no user associated with this type of credential, so granting granular permissions to a particular user won’t affect anything.
