Need advanced settings help

I have a the gl-mt1300 beryl router and i bought it to make my iPhone hotspot a router so i can connect my Xbox one series s via ethernet cable from router. the phone is connect via usb cable to router. when connected on my Xbox in network settings it says ipv4,upnp not successful and strict Nat type. I’m trying to get ipv6 upnp successful and preferably open Nat type but moderate will do also. is there any way to make this work with what i got ? if so how, also the router seems to drop connection from phone constantly but I’m not sure why. I plugged the same cord that I was using to my laptop and my regular charging block and it works perfect. thanks for all the help
