Building, integrating, or customizing apps and workflows within Microsoft Teams using developer tools and APIs
The Metered Teams API for accessing online meeting transcripts does fall under the category of onlineMeeting as listed in the Microsoft Graph throttling limits.
Ref: https://learn.microsoft.com/en-us/graph/throttling-limits
Regarding the implementation of a custom throttling policy on Graph APIs accessed using your application's generated access token, it is not possible to implement custom throttling policies on a per-user basis. Microsoft Graph has built-in features that handle throttling automatically.
To achieve your requirements, we recommend you give your feedback in Teams Feedback Portal.
