Additional throttling headers are missing in /teams endpoints.

Question

Given :

In the section, Additional Headers

Below four additional headers are given,

1. x-ms-resource-unit
2. x-ms-throttle-limit-percentage
3. x-ms-throttle-scope
4. x-ms-throttle-information

Observations :

Teams endpoint:

I have checked (Even throttling scenario)

1. Get channels /channel
2. Get tabs /tabs
3. Add tabs /tabs

But never seen given additional headers in response headers of teams endpoints.

I have seen following headers:

• x-ms-resource-unit :
  Received as response header when requested to /user or /group endpoints.
• x-ms-throttle-scope and x-ms-throttle-information
  Received as response headers when request of /user endpoint get throttled.
  i.e. Tested by hitting /checkmemberobjects by sending around 1000 requests per second.

But I have yet to observe x-ms-throttle-limit-percentage as header
