Been question about POE and switches

Hey group. I purchased and just setup a ring security cam using a Wasserstein PoE injector to power and transfer data.

Before I spend money on an additional Ethernet switch, can my Wasserstein PoE act as a switch also? I simply need more Ethernet ports for the house, but almost none need PoE.

If I CAN use it, should I plug into the LAN side, and not the PoE side?

Edit: tried to edit title to say “newb” but apparently I can’t do that? I’ve been in my 120 degree attic all day, so I’ll claim heat stroke.
