Alain Inspired me to start this project
Mitchell helped me with his app "ESP Alerts" which lets you choose which app will send notifications to the Esp32 chip. I couldn't use my Amazon tablet, which gave me some errors but Mitchell gave me an APK and it downloaded successfully, it works as expected. The ESP32 and tablet communicate well.
Now I plan to use the Apple Notification center service or ANCS which is a standalone Bluetooth service, there is no need for an app to relay notifications to the ESP32.
