How do you connect to Hypixel on Xbox?

You must've heard of GeyserMC.

Unfortunately, due to the implementation of Hypixel anti-cheat, you should not connect to Hypixel via Geyser. As per the time of posting, you still cannot move in Bedrock Edition. You can connect, but you won't be able to do anything meaningful.

Furthermore, in terms of game balance and feature disparities:

• Bedrock has a further hit distance, allowing you to interact with things further than vanilla Java players can.
• Bedrock movement has extremely high inertia (how fast you go from moving to stopped), whereas in Java, it is lower, especially when flying.
• You can't click links in chat, which Hypixel uses a lot of, and commands are sent in a different way to servers.
• Not all behaviour in Java exists in Bedrock, for example: Buttons have no hitboxes in Java, but do in Bedrock. Entity cramming and physics are also slightly different between the two.

And: Hypixel has publicly stated that even though it isn't banned, any automated bans or false positives from this will be treated as if it was a banned mod. (Basically use at your own risk)

Oh, and you need a Java Edition account too.
