   I'm not altogether familiar with Telethon (I didn't know that as of today), so this answer may be wrong.

   You passed a symbol to Python-side. But the code in Python-side couldn't get the method handler from Ruby-side.

   As I see in the document you mentioned, the sample code in the document passes a function itself:

   from telethon import TelegramClient, events
   
   async def handler(event):
       ...
   
   with TelegramClient(...) as client:
       client.add_event_handler(handler, events.NewMessage)
       client.run_until_disconnected()

   So, you need to pass the method itself, don't you think?

   However, the handler function above is defined as an async function.
   I think that this library cannot use from PyCall as is if the handler must be an async function. Because PyCall doesn't have the way to make a Ruby's callback an async function.
