Hello community, has anyone ever connected a SharePoint Online list through REST API in SNAP? I keep getting a 403 error, even though the URL is correct, the user credentials are accurate, and the user has all the necessary permissions. Maybe one of you has a tip on what I might be doing wrong...

Here is what i have done so far to Implement the OAuth-Szenario: 

1. Register SOTI in Aure AD

2. Build Client Secret

3. Configured API Access for Sharepoint

The next Steps should be the following:

request Token

implement Token into the REST Configuration
