Email link in Popup in AGOL

Question

I am using AGOL. I have a attribute column called email that contains people's email addresses. How do I make 
that email column a hyperlink to the actual email address in the popup for my polygon.
I am assuming I have to do this in Web app builder as a custom setting and cannot do it in the mxd before I publish.
Is that correct? Any links in how to do this in WAB would be appreciated 
Thank you.

Here's a blog post that shows how to configure your web map popup to have an email link.
