Gosund smart switch setup

I'm trying to add some Gosund smart switches to my network. I already have smart outlets from the same company working perfectly. Gosund documentation says I need to turn on a 2.4 ghz network to initially connect the switches, and then I can go back to 5 ghz once they are running. I don't recall doing this with the smart outlets, but looks like I need to since the switches are not being recognized by Gosund when I try to connect them right now, and my Orbi is on 5 ghz. Anyone know how I set up a temporary 2.4 ghz network on the Orbi RBR50 to get these switches going?
