How to make a field mandatory dynamically depending on the selection of another field(checkbox)? So if the checkbox field is checked by the user, the concerned field should become mandatory else optional.

I don't think this is possible even with the use of dynamic look up based on values, I would request you to raise an idea and our Product management can take a look at the same.
