In my knowledge domain, that's actually possible on iOS, but it will cause more privacy issues for sharing data between different apps, and also the clipboard issue. Apple has been pretty restrictive about inter-app communication for good reasons, but it does limit these kinds of automated workflows.

As you mentioned with that situation, I think Apple and Google may have better power to optimize the OS system if we only do it on the local device. They have the deep system-level access that would make this kind of seamless automation work without the privacy and security trade-offs that third-party apps face.
