On the latest version of Oxygen OS, Oxygen OS 16.1 or 7.200, they fixed icon packs, and now you can keep scrolling until you find the icon that you like. You still can't search for them, but at least they all load, unlike before, where only a certain amount of icons would load and you couldn't see or choose all the icons when changing an icon for a specific app.

On earlier versions of Oxygen OS, icon packs could only load a certain amount of icons before stopping. But now, on the latest 7.200 version or Oxygen OS 6.1, they fixed it, and now all icons load. You still can't search for them, but you can at least see all of them and just keep scrolling until you find the icon that you like.
