API for Synchrony or websocket server on Forge

Hi!

I would like to offer real time collaboration to users in my custom UI confluence app but avoid hosting my own websocket server, keeping all data in the Atlassian space.

I saw that https://developer.atlassian.com/cloud/confluence/collaborative-editing/#the-synchrony-api was a thing which would have been nice to use. Anyone knows if there are any plans to expose APIs for plugins on connect/forge?

Otherwise is it seems like running a websocket server on Forge should be allowed Are websockets supported in Forge custom UI? anyone successfully done so?
