Push notifications in AMP pages.

### Description

When we add push notifications for non-amp pages via pushEngage then there comes a prompt on the same page for allowing or blocking the notifications but for AMP pages when we implement this there comes a button king of thing on the page for accepting the notifications, also when it is clicked then the popup opens in a new page which isn't a good user experience. Can the push notification thing be like a normal page even on AMP pages? Can this feature be implemented?

### Alternatives Considered

The popup should come on the same page and there should be no button on the page itself for sunscribing.

### Additional Context

_No response_

The issue names AMP pages and the PushEngage integration but no files, tests, or entry points. Start by locating the existing PushEngage implementation and its AMP-specific flow, then compare it with the normal-page behavior. The work is complete only when the desired same-page subscription experience and its feasibility are established.
