Passing variables chosen in adaptive cards from Bot Framework Composer to PVA + herocard styling

Hi again everyone,

I am trying to pass a variable from Bot Framework Composer back to PVA, I have an adaptive card that shows a list of options for a user, when they pick one I want to be able to send that answer back to PVA without showing it as a message in the chat. Currently in bot responses I just have:

- SWITCH: ${day}

- CASE: ${0}

-${conversation.day_choice}

- CASE: ${1}

-${conversation.day_choice}

- CASE: ${2}

-${conversation.day_choice}

- DEFAULT:

But that just returns 'numbers' based on the case-number in the response so it will just say '2' in the chat if the user chose the second option.

I want to pass the choice as a string to PVA, then let PVA use that choice to continue down into the decision tree. Any ideas on how do that? I could find very few examples on this on the internet, it may be a little niche...

I found: https://powerusers.microsoft.com/t5/General/how-to-get-user-value-back-to-PVA-from-Bot-Framework-Composer/td-p/1188409, but that didn't quite answer my question in a way that I could get to work.

So tl;dr: user picks an option from adaptive card, save option as a string and give that back as a variable to PVA, use this variable to determine the next path.

Additionally, my vertical list which I pinched from https://docs.microsoft.com/en-us/power-virtual-agents/advanced-bot-framework-composer-example2 obscures some of the text if the options are too long, any workarounds around this?
