Enable both 2G and Wifi-5 in my Huawei router

I currently have a Huawei AX2S router.

This router defaults to a Wifi-6, 5G network, but it does support Wifi-5 and 2G networks.

I have an older phone that dosen’t support neither Wifi-6 nor 5G.

The issue, however, is that i can’t figue out how to enable a network that is both Wifi-5 and 2G. I’ve checked the router’s configurations, but there isn’t an obvious way to enable it.

Thanks in advance!
