What are the exact per-app-per-tenant and per-app-across-all-tenants throttle limits (rps) for GET /users/{id}/chats and GET /chats/{id}/members?

Question

1. The Teams service limits docs show "Other GET API calls = 30 rps / 1500 rps" but GET /users/{user-id}/chats API and GET /chats/{id}/members aren't explicitly listed.

   Are these are actual limits of these two apis. Is there a cost model (like Resource Units) not documented for these endpoints?
   Anywhere is it officially documented?
2. "Does the Teams service use a token bucket algorithm (like Identity/Access) or a different throttling mechanism? The docs don't specify." Anywhere is it officially documented?
