You could use gains for when they tap the overlay and labels/goto as Dara mentioned to go back to the main search of it along with using Enable/Disable Choice Options with Conditions
You could use that type of coding for if they’ve tapped that overlay then it’s removed so others can be tapped too and you can use this type of coding to make it so that all of them need to be tapped in order for them to proceed on with the story so that none go untapped.
i feel like I said the word tapped one too many times lol
