Use "select many", store and insert text

I would like that participants can “select many” (several answer options). I would like to store the answer options (text) in a variable so that later on, the chatbot can repeat the answer options chosen. I tried to simply add the variable in the text, but then it adds commas (,) for each answer option that were not selected. Please see the screenshot. How can I manage to do this properly?

Many thanks
