Arcade expression to append select multiple choice from survey123 in pop-up

[leahmaps]

Hi!

I am trying to work on an arcade expression that will append answers from a select multiple question from survey123. 

This is a snip of the options that are given in the survey. Users can pick as many as desired, with the option of their own in other (when any of them go into the database, they have no spaces, which is another fix).

What I want to do is have an expression that will list out whatever people have chosen, with 'other' (if filled out) being at the end. What would be the way to create a list that will write out all options per submission.

Thanks!
