    Join any Minecraft Bedrock Edition server IP on Xbox One

    On Minecraft Bedrock Edition, players on Xbox One, Nintendo Switch, and PS4/PS5 are limited to playing on 'Featured Servers' approved by Mojang/Microsoft. These players are not able to join servers via an IP/address. This is an issue for me and others, as the server community on Java edition was one of the major parts that made Minecraft what it was, and what also made the servers that are now considered 'Mojang Server Partners' what they are today. I wanted to fix this, so I made a solution that anyone can set up easily.
