Thanks for the contribution ❤️

I'll talk with the team in regards whether we prefer whenUndefined or scopeRequired 👍.

What I don't understand is your comment in the discussion board where the reverse effect and condition did not work for you, i.e.

am pretty sure I tried the reverse rule and it didn’t work for me

Looking at the code here and the suggested improvements of scopeRequired only applying in the true case, this seems for me to indicate that reversing the effect/rule for the undefined case should also have worked. Can you verify what's going on?
