1. Done.
2. I considered the use of tdlib but requiring dependents to install tdlib C library. This is a barrier. Instead, I propose that we run our own service that will support username resolution, just as we relied on PWRTelegram API. I am not entirely sure that tdlib supports username resolution? (cart before the horse 🤷‍♂️)
3. We should also have the service integrate the websocket bridge (we can re-use @GingerPlusPlus work).

Sure, I'll see on how we can get that up and running.

Any updates on username resolution? That would be super handy.

You need to use ContactsResolve with MtProto to get username/phone -> userId. userId -> username is also possible.
