Populate Adaptive Card Choiceset with single column array
I have the following Flow;
Here I am looping through the rows (3 in total) of an excel spreadsheet and I'm putting certain column values into 'Compose 3'. In the Filter I am then removing any blank columns so that I have a single column array of values. What I would like to do is then pass this single column array to the ChoiceSet option in the Adaptive Card, a bit like the below;
I have tried many things but cant get it too work. Basically just need the array of values as separate options in the Adaptive Card drop down box. Any ideas?
