Where is "All packages" in the Package Manager?

So, I was trying to add 2D Lights to my 2D game and Brackeys told me to go to Package Manager → All Packages. However, all packages seem to have disappeared? ( I can only see “Unity Registry”, “In project”, “My assets” and “Built-in” ). The weirdest thing is: I think I recently saw the “All Packages” thing when I was adding tilemap a couple of days ago… I tried enabling package preview and reverting my Layout to normal but it did not work. Can anyone help?

What I see at “Package Manager”:

Hi. OP here. Apparently, Lightweight RP was changed to Universal RP and Unity Registry is the new All Packages.
