<p>My PyQt5 app so far runs well. But trying to add functionality
requiring asyncio results in failure.</p>
<p>I tried to integrate the telegram-bot function (pip:
python-telegram-bot). When using the old version 13.15 I got it
running, but I am swamped with deprecation warning. But the new
version 20.6 mandates the use of asyncio, and here is where I lack
understanding; I can't get it to work.</p>
