[Question] Telegram Apps authorization transfer

[KozlovKV]

Hi everyone!

I've faced with some specific case while developing chats aggregation native app.

I want to authorize user using official Telegram API, get basic dialogs info and then open Telegram Web instance in Webview with user already authorized in my app.

Of course, I use forked self-hosted Telegram Web instance with common API credentials for my app and Telegram web fork.

Is it possible or may be implemented quite simply?
