Respawning an item

Hi so I am trying to make items respawn after 5 seconds. The problem is I have no idea how to do this. There are multiple items I want to respond after 5 seconds after picking them up. I got the picking up part right but not the respawning. Thanks for the help!

use Unity’s Invoke function to respawn.
