Is "switch to other business" idiomatic?

People often perform a double-click on a Zoom link and switch to other business.

In the above sentence, I intend to say people click a Zoom meeting link, and although their computers are attending a meeting, they often switch to work on other things, i.e., not paying attention to this meeting.

Oxford Learner's Dictionary has

[uncountable] important matters that need to be dealt with or discussed:

He has some unfinished business to deal with.

as well as "get down to business", "go about your business".

Does "switch to other business" idiomatically mean "switch to work on other things"? If not, is there any phrase meaning "not pay attention to something and work on something else"?

Solution 1:

I don’t think “switch to other business” is the right thing to say, as that phrase has more meaning than just switching to another activity.

I would probably just say something like:

People often click on a Zoom link and then do other things in the background.

To me this is very idiomatic.

“In the background” here implies that the fact they are not paying attention to the meeting goes mostly unnoticed.
