Bug in Jest js tests: react-modal: No elements were found for selector #root

I am trying to create SelectColumn.test.js similar to Summary.test.js

https://gitlab.com/sosy-lab/software/benchexec/-/blob/SelectColumn.test/benchexec/tablegenerator/react-table/src/tests/SelectColumn.test.js

But unfortunately not successful, I tried all solutions from code forums. But seems I am doing something wrong.

Result: failed

Expected result should be: passed

Error:

react-modal: No elements were found for selector #root.
