Dice say that if someone wants to be able to purchase your ticket then you can sell it to them via their platform at no cost to you. i.e. you can return your ticket if someone wants it.
I do not know of any ticket that can be returned "just because".
Even a theatre or opera will accept returns only if they have demand for them.
Now compare to the majority of platforms that don't allow returns even when there is demand for them... or that will charge late arriving fans a higher price than face value for the returned tickets.
