FR: add support for existing threads

Please consider adding support for accessing existing threads via id.

I think that would be useful. Do you suggestion on how to switch threads? Via Telegam bot command or natural language?

[dv0zn3r]

I think using a Telegram bot command (something like /switch_thread thread_id) would be a straightforward choice. This would allow to switch threads by simply typing a command with the thread id users want to switch to. Then the next question would be how to manage id threads if there are numerous, and whether that is something to consider at all.

I think it's possible to summarize a thread before leaving and use that as the key to come back later. I want to avoid the slash command though, because it's too robotic and not user friendly 🙈
