Further work in raspberry pi iot project

It is a raspberry pi iot project where there is a motion sensor that detects motion and captures image on motion using a usb camera. That captured image is then uploaded to amazon s3 bucket and stored in raspberry pi as well. It also has an amazon rekognition script which detects faces and sends that image to flutter mobile application, if it is a known person from the collection then it labels that image as 'known' otherwise 'unknown' in the flutter mobile app.

I need some help in changing the amazon rekognition script in pi and sending that image to a new app that I will provide.
