IDFA tracking using att framework

I’ve been trying to solve this for some time And wondering if anyone else has come across this.

using att framework and receiving user consent to use IDFA. is It possible to know when a user has entered another app on the same device ?

flow:

  1. user consents to att framework in App 1 on iPhone
  2. user opens app 2 on iphone
  3. will app 1 know that user has opened App 2?
