Load MS Dynamics CRM 2016 as an i frame inside other web application

What I am trying to do here is, we have a requirement which needs MS dynamics CRM 2016 to load as an           i-frame inside another web application. CRM is on premise

While doing so, I am getting following error in Developer options in browser:
