Set default value for list in ReactJS

Question

I'm trying to set default value to datalist using useEffect. Tried to set it (line 16) with setSelectedEmployee(employees[0].id);

I also tried (line 64) to set default value with, no success.

value={employees[0].name}

Here is working example: https://codesandbox.io/s/prefill-list-73c4sd

Any help would be highly appreciated.
