When I use Wix forms, there’s no place to add regex, the same way I could with a user input field. How can I add validation/formatting rules regex for wix form fields like phone#, postal code etc? Looks like the email field already has one built-in. If I have to add it using Javascript, does someone have the code for me to add to my site?

Help.
