Displaying a list of Push notifications sent to the user?



how would I display all the push notifications sent to the user in his app (i dont mean code wise)? Does Ionic has an API to fetch pushes sent to this user? Does Ionic has an API That user can delete his push notifications if he wants, some or all of them?

Or do I have to track all that in my own DB?

Something similar to Pushover app (if you are familiar with it).
