How do I export animations from Blender to UE5.1.1?

Hey! I’ve been trying to export rigged arms for a FPS and losing my mind haha. I’ve made a placeholder animation (static pose holding a gun) to test exporting one over to Unreal from Blender, and it works all fine and plays in Blender but doesn’t in Unreal. I’ve searched online and watched a ton of videos trying all different export+import settings, renaming the rig, animations moving the bones directly vs. IKs, and nothing seems to work and at a roadblock.

I’ve put the blender file and screenshots of my export+import settings in this link: BlenderUnrealRig - Google Drive

Does anyone know what the issue could be? Thanks for any help in advance!
