Changing the “Click to Call” button to an Email link

We would like to remove the “Click to Call” phone number that the Meeting Guide App displays under the “Connected” reporting area/district name. When a meeting is clicked on from the app, the bottom of that page shows the following:
“Have a question or feedback about this meeting?
Florida Area 15 District 3
Lakeland, FL 33813, USA
Connected”
Just below this is a “click to call” button that we’d like to either remove or change to a click to email button.

Thanks everyone in advance for any help you may be with this issue.
