How do I add a pop up on click?

Is there a tutorial or FAQ that shows how to make a form show up in the pop up in v6? I've enabled the pop up and added in a class in the "Display on click of" but I'm not sure how to actually call that class. I've tried:
​
<a id="popupform" href="#popupform" class="popupform">Click to Open</a>

I added the pop up to the page using the shortcode: {chronoforms6}management-quote{/chronoforms6}

​
What am I missing?

Try the modal / popup form demo

Can you provide a link? The only one I've been able to find was for v5 and looked like a jquery modal instead of the pop up built into v6.

New form -> Demo form

Oh! Gotcha. I will try that. I didn't know that existed.🙂
