You can follow the first part of this article from Microsoft Learn.

Are you sure you set Content-Type to application/x-www-form-urlencoded in the headers?

• For the method, select GET (1)
• For the URI, enter https://login.microsoftonline.com/<TENANT ID>/oauth2/token (2)
• On the Headers tab (3) add Content-Type key and application/x-www-form-urlencoded for the value (4)

• Switch to the Body tab, and add the following keys and values.
  • Select form-data
  • Add grant_type key, and type client_credentials for the value.
  • Add client_id key, and paste the value of client ID you noted down earlier.
  • Add client_secret key, and paste the value of client secret you noted down earlier.
• Select Send to send the request to get the token
