i can't join lan games on xbox one

I can not join lan games this happens in the latest official version, if I do not have gold I can not join or even the friends who are playing come out, then I tried to get that person to send me an invitation, send me to buy Xbox live gold and it was a world in lan, we were both connected to the same network, this did not send me until this latest version 1.16.0 and that bothers quite a lot why it is assumed that the in-game lan is does not need gold because it is on your same wifi network
