Communihub Email Open Tracking - How Can I track which leads/contacts have opened the email most

I use communihub as primary emailing tool to our leads and contacts because of the ability to track who, when, and how many times the email has been opened. At this time, I’d like to be able to sort my list of leads/contacts by number of times an email has been opened, engagement, etc. which will help us prioritize our follow-ups.

I’ve created the integration already that changes a status to “Email Read” after the first time the email is opened, but unable to track engagement beyond this point.
