I have a sharepoint list with a multi select column and I need to get that data and add it to an Adaptive Card as a single line of text. I can't use variabes and append each value to a string because I have an "Apply to each" loop runnning concurrently with a degree of 50, so the variables get caught each up with each other.

The output of the column to the adaptive card should be something like "x, y, z".
