So for telegram, what I want to do:
1. Receive from webhook
2. Format the message the way I want, message + thumb (right now, because emby has a limited info, I parse the info and search in emby api or themoviedb api)
3. Send to Telegram/Discord/Facebook/Whatsapp bot using their api
Yeah maybe for the people that don't create as service like me, using docker is not the ideal, but for my scenario is just perfect.
Anyway, is the way that webhooks works, i guess for the people that don't want use it as webhook, they still can work with plugins.
