Support Compose AddIn on Mobile
According to this...
...Addins are only supported for message read, on mobile. Can we please have a MobileMessageReadCommandSurface ExtensionPoint, so that we may create an addin for message compose, on mobile.

I'm excited for this as well. Once you are able to share, I look forward to hearing about a timeline for adding MessageComposeCommandSurface to the mobile API.
