Track calls to a phone number with Google Tag Manager

I have a client that is using Google Ads in combination with Google Tag Manager to replace a phone number on their website with a Google forwarding number to track conversions using call length. I’m interested in trying to use Zaraz to increase their site performance and wondering if this type of conversion tracking is possible to setup with Zaraz? Dynamically replace the static phone number on the site with the number from Google?
