2. Go to "Window" -> "Package Management" -> "Package Manager"
3. Download a few deprecated assets (examples - "Snaps Prototype|Sci-Fi/Industrial" or "Snaps Prototype | Office"
4. Select the "My Assets" section in the Package Manager window
5. Select your downloaded deprecated asset
6. Observe the icon in the help box section
