How to detect the "Change Scene" action from Reality Composer in Xcode

I have a Reality Composer project that has two scenes. In the first scene, I post a notification from Xcode to trigger an animation and then change the scene to the next scene. This is done using the Change Scene in the Action Sequence.

In the second scene, when the user taps on an object, it should send a notification to Xcode using the Notify action. How do I set the .onAction in Xcode for the second scene if I switch to the second scene using an Action Sequence from the first scene? Thanks!
