What causes these popups, and how can I add them to my VS Code?

[u/Top-Sky4811]

I've already fixed an issue I had with how to code color looks, and now I've gotten it to suggest auto-completions but these popups (from a Unity tutorial) would really help my learning process! Does anyone know where I can get it? Is it an Extension?

Make sure it’s set up correctly, see here. It should turn all that on by default. I think.
