Rigging Metahumans

Hi, I am fairly new to unreal engine, so I am sorry if it may seem like a silly question

But I am making a project on UE5 Preview 2, and I am trying to rig my metahuman to use basic animations with Mixamo.

Upon following the video above, when opening the Skeleton he uses “Set up rig” to set a humanoid rig to his character, I can’t find that tab in my version of unreal engine, does anyone know if things have changed ?

The retargeting process has changed with UE5 preview 2.
