The Lubuntu 22.04 LTS release announcements said I felt rather clearly
Lubuntu 22.04 LTS will be supported for 3 years until April 2025
It is covered in the manual; the Lubuntu 22.04 LTS manual was dropped, so I’ll provide a link to the Lubuntu 24.04 LTS manual instead

It’s a little finicky possibly, but just hover where it belongs until you see a green + appear which tells you where you can drop the app shortcut on the Quick Launch area.
