Push Notification Setting Page

How can i make a page inside my App where my users are given an option to select which notification they want from my WordPress Blog posts. like news, sports, Food etc. I don’t know how to create this page for users and link it to my push notifications setting? any tips please. Thanks

Any Suggestion Please?

You can start by creating a page with checkboxes and save the user preferences in a table of your database.
From that you have to make a script that checks users preferences and make a push notification to them
