AICore and AI Edge Resource Synchronisation

Hi,
I can see that new AICore system service/system component is available on selected Google Pixel models. Also AI Edge provides API for accessing TFLite and MediaPipe framework for accessing underlying devices compute resources.
How resources like GPU will be shared among both of these ecosystems , on which layer this synchronisation/serialisation will happen ?
I was expecting it at NNAPI but I can see NNAPI is getting deprecated from Android 15.
For app developer does it matter and do they need to synchronize themself in some way or Android framework will take care of it somehow.
Use case is app downloaded from app store uses lets say tflite (liteRT) APIs and google’s internal services are using AICore then which feature gets executed and how synchronization will work.
Any reference doc for understanding this will help.
