Switch in AP?

So I’m trying to handle the influx of family at home with corona and the amount of needed hardwire connections. I currently have my router running an AP farther away in the house, I need to hardwire 3 new devices that are near the AP. I got an unmanaged gigabit 8 port switch from a friend and having been having some issues making it work for me so I’m wondering if it’s because my set up won’t work.

So what I’m wondering is can I plug the switch into the extra port on my AP to then have 8 ports in this area of the house to use? Or does the switch need to plug directly in to the router, causing me different problems to solve?

Thank you for answering what is probably a dumb question!
