Zoom annoyingly captures focus when joining to a call

I click a link in my work chat. While the zoom is starting and connecting and joining, I would like to continue writing something to my work chat. Instead, Zoom captures focus every second, so for about 15-20 seconds I am unable to chat or do anything else. 

Any idea why such an annoying feature was implemented?

Zoom 5.14.2, MacOS 13.1
