This looks like three lines symbolizing a paragraph. The tab has a Star (☆) as the label. Edge refers to bookmarks as "favorites." This will immediately delete the bookmark. If you delete a folder, all of the bookmarks inside will be deleted as well. You cannot delete the "Favorites Bar" folder.

TL;DR in Indonesian:
Sentuh atau klik tombol “Hub”. Sentuh atau klik tab “Favorites”. Klik kanan (atau tekan dan tahan) markah yang ingin dihapus, kemudian pilih “Delete”.
