I've read lots of docs and different posts, but I can't get the right access token to read my own OneNote via api.
- I have MS account and app in azure portal.
 - In graph-explorer I CAN read my OneNote.
 - If I copy access token from graph-explorer, then my code works fine.
 
BUT:
- If I request access token from 
https://login.microsoftonline.com/{tried 'common' or my tenant_id here}/oauth2/v2.0/token, then it does not work: 
The OAuth token provided does not have the necessary scopes to complete the request. Please make sure you are including one or more of the following scopes: Notes.ReadWrite.All,Notes.Read.All
- I created app in azure portal and gave it all read permissions, which I found ( for both one-note and ms graph APIs, both delegated and application... just for test) and generated secret
 - I'm trying following request:
 
token_request_data = {
    'client_id': 'id from my app',     # also tried 'common'
    'scope': 'https://graph.microsoft.com/.default',  # other scopes cause errors
    'client_secret': 'secret from my app',
    'grant_type': 'client_credentials'
}
Perhaps somebody could give me a clue what I'm doing wrong ? :)
Sample request via graph explorer:
