Wireless Charger not working out of box

I got the wireless charger hardware kit. Before proceeding further I tested the charging coil to ensure it would charge my phone. It would not. I tried different chargers, fast chargers, slow chargers. I tried on a galaxy s20 and an iPhone 12 mini.

There’s some kind of switch on the board I tried toggling in each configuration to no avail.

Is there anything else I’m missing or did I just get a defective unit?
