Can asyncio be combined with PyQt5?

[ullix]

Thank you, I was afraid of such an answer.

Isn't it of convern that two major developments - PyQt and asyncio - 
exclude each other' use? In particular both of your links seem to 
suggest that a combination is possible.

Rewriting the telegram-bot lib is not an option for me, and asyncio does 
not seem a stringent necessity, as its older version runs without it.

Thanks again
