After looking at this in more depth (including speaking with support and reviewing the relevant documentation), it’s clear that some important functionality has not been integrated into the GD Avada Builder Elements. Specifically in this case, the ability to choose which fields appear in the GD > Output Location builder element (formerly would have been a widget). That’s the missing piece that would at least allow the hiding of the email output.
However, I still hold that the email display needs to show a button that open a submission form and not the actual email address.
Furthermore, trying to reconstruct the output using GD > Post Meta won’t work because that won’t display business hours in the right way.
this is not done via Avada Builder Elements.
In order to hide the email from the output location widget, you need to go to Places > Settings > Custom Fields click on the email field and remove: Detail page sidebar from the option: Show in extra output location.
The only way to add a contact form to the listing for the moment is by using Ninja Forms.
