how to show a confirmation message when performing action by using dynamic link?

Step 1: go to my existing feature request thread
Step 2: click "like", click "i have this question too", add a comment detailing your use case in case anyone at Appian ever sees it (and adding a comment will float it back to the top of Community, which might help)
Step 3: wait long enough for this to make it off their backlog. I've been waiting 3 years so far, so....
Note: I do like the workaround that @harshjan already posted above, though it's a lot of manual work and juggling to make sure that sort of thing functions as desired, when (to me) there should just be built-in functionality that replicates how it works for buttons and a!submitLink().
