How can I change this so that I can play multiplayer in Minecraft?

I have a problem with Minecraft Java Edition. In multiplayer it comes…

Where can I change this in the account settings? Or does the administrator of my family account have to do this?

Mojang is currently maintaining its servers and you can't access the multi-player and realm functions. But they also announced that.

Ok but I have it with a Microsoft account… I have to ask my friends but I think they can play…

I don't know my way around very well, but I think the administrator has to do that.

OK thanks
