Request missing Mattermost API methods here

[bvdcode]

Hey everyone 👋

The Mattermost API is pretty large, so I’m adding methods by priority and based on real usage.
If you are using Mattermost.NET and need a Mattermost API method that is not implemented yet, please leave a comment here and tag me: @bvdcode
No formal template needed - just briefly mention the method or endpoint you need.

Thanks!
