Thanks @marek-mihok. Do we have any alternative solutions? Also please add accompanying unit tests.

Do we have any alternative solutions?

After exhausting attempts I was not able to find any reasonable & working solution.

• I was trying to set default selected values while creating new Selection object instead of the useEffect but without the result since FluentUI does not support other way of making selection other than using functions setKeySelected, setIndexSelected or setAllSelected.
• The possible solution is also to emit the select event only on mouse click, but this includes implementing the custom behavior for both checkbox and row mouse clicks.

Do you have any ideas @mturoci ?

Also please add accompanying unit tests.

Done ✅

I tried running the unit tests, but one did not pass.

Based on a quick glance, the assertion seems wrong so I fixed it, but please have a look at whether it indeed makes sense since you spent more than 2 minutes on this task.

Also, I introduced a different solution for the original problem, let me if it looks good to you.

Thanks @mturoci! I went through your solution and it is looking good. Also I tested manually multiple scenarios and all is working as expected.
