How to implement favorite/bookmarks in Ionic5/Angular

Hi. I am trying to implement a favorite/bookmarks page in ionic mobile app. It contains just texts. The pages are in an array of objects, so clicking on “add to favorite” button will push an object of {title: “page1”, url: "/page1} into an array in a “my favorite” page where I can view them at the front end. I’m using Ionic5/Angular. After everything, when I refresh, it will not keep the pages in the favourite/bookmarks since I am not implementing a local storage functionality on them. So I need help on how to implement it and also be able to remove the added pages from the storage.

Thank you
