Thanks for opening this new feature PR!

The PR needs an issue associated with it describing the feature and also a change log item. Would you mind checking out the contributing guidelines and updating?

Also I think this is a new feature so the issue should be marked X-Needs-Design and X-Needs-Product so that it gets product/design sign-off before inclusion.

Btw, the failing compile check is because it depends on changes in the SDK (matrix-org/matrix-ios-sdk#1307)
