Android application for transfer of push notifications/SMS.

It is necessary to implement an Android application to transfer all incoming push notifications/SMS to an external endpoint.
Please leave applications from those who have previously implemented something similar, as there have already been 2 performers on this task who did not show results.

There is a Figma mockup. There is a Kotlin application written and its source code. The finished application works with bugs in sending, it is not possible to use it — unstable.
Writing from scratch based on the example of the finished one or editing the existing code — at your discretion.

The main requirement for the application is its stability. All incoming push notifications should be redirected. There should be no delays in sending for an hour, no application hangs (within reasonable limits). It is clear that for stable operation, specific conditions are necessary for the phone (stable internet, screen turned on, no heavy load from other applications).

The application will be used both with real devices and with emulators.

As an alternative in terms of functionality, we consider GooglePlay MacroDroid.
It works quite well, but there are nuances.
