Is it possible to enable the functionality that limits the ability for users to zoom out too far or too close? In other words, the ability to set the allowable extent of a web map.

I have read that this functionality IS available in one of the Experience Builder Templates. Please consider exposing this functionality to the Blank Grid Template.
