title: I need a guide about Screen Tracking in Firebase
body: <p>I am trying to set Screen Tracking in my App. </p>
  
  <p>As far as I understand, It requires each different window to track user's activity. </p>
  
  <p>Here is my question.</p>
  
  <p>Can I set different Screen Tracking code in Pop-up window(Example: Store Pop-up)? Or do I need to make a whole- different window to track user's activity properly? </p>
  
  <p>Thank you.</p>
