I am configuring the Pre-Incident Plan Solution for our Fire Departments. Within the Experience Builder App that is included that is titled "Pre-Incident Plan Manager" there is a Feature Info widget that has a button with the text "Assign Plan." The button is formatted with a mailto link. I am trying to change the content of the mailto link however, I cannot access the formatting for the button.
In other testing I have done, I cannot even add a button to a Feature Info widget. It seems as though ESRI has "locked" the button somehow. Any ideas on how to access the settings for the button would be greatly appreciated.
