Implement notification quick actions to deny or accept a push request.

[Luc1412]

What to change?

Implement quick actions to notifications to quick allow or deny a push request,

Why

This adds the convenience for users to accept requests without opening the app or trough a connected smart device like their laptop or smart watch.

Considerations

While this adds convenience for the user, it also introduces some problems.

• It makes it more likely that the user accepts a request by accident
• The notification message itself needs to provide all necessary details for the user to decide on accepting or denying the request
• When we add an extra challenge on accepting a request like proposed in Implement user challenge #4 we can't accept the request right away, but need to bring the user to the challenge screen.
