You’re using abstract terms like ‘hijacking’ and ‘product handlers’. You’ll need to provided code that shows how you’re doing anything now, describe what methods you’ve been trying, describe what results you got compared to the documentation, explain how you’ve tried different techniques to resolve any problems etc. Refer to the How to ask a good question thread.
It seems that, rather than follow the guide I recommended and discover the Power-up framework capabilities yourself, you’re asking someone else to be a type of research assistant, to pore over the documentation for you, write a dummy PowerUp and then do all the testing on your behalf, then report back to you their findings to provide this ‘definitive proof’ you seek.
If that is the case, then I’m not able to help any further.
Best of luck.
