Connecting Avare EFB to MSFS

I did all you said in order. I get connecting to msfs in right corner as you said. On Avare my gps preference choices are: Avare apps only - built in gps - all available. set originally to avare apps only. didn’t work. tried all of them didn’t work on avare, Also the last step you show I see is "in same preference menu location. under “external wifi port” enter 49002. I don’t see this preference anywhere. Please help? Thamks
