<p>Thank you, I was afraid of such an answer.</p>
<p>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.<br>
</p>
<p>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.</p>
<p>Thanks again</p>

<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>
