What are the rate limits for the get channel messages subscription?

Question

What are the rate limits for the /teams/{id}/channels/{id}/messages subscription? I'm using delegated permissions to create subscriptions for messages for teams channels, I see https://learn.microsoft.com/en-us/graph/api/subscription-post-subscriptions?view=graph-rest-1.0&tabs=http the channel messages subscription is not explicitly mentioned as being metered. Is it metered? If so, does it support model B? If not, what are the rate limits here?

Answer 1

/teams/{id}/channels/{id}/messages isn't metered and thus does not support modelB.
Rate limits for change notifications are the rates for the events coming in i.e., the number of messages coming to a channel.

Thanks,
