Edit rights on public shared links

This is the one feature that might make us go to the competition.
We are about to onboard users on our product and intend to do co-design sessions with them using whimsical.
The problem is they are forced to create an account on whimsical to see and comment boards and it creates friction.
The 2nd problem is they cannot edit the boards we share with them.
It doesn’t make sense to create real user accounts for them as they will mainly be participating on a few boards for a very short amount of time.
It would be awesome to just be able to privately share a link with edit rights to a board without any account creation friction, like a google doc.

I would agree with this as well.
It might be useful for us in certain situations.
