Import a simple FBX from blender as a single object?

Hello

I have been trying to export a simple crate I made in blender into UE as a single object. However every time I try it seems to have all the original squares I used to make the crate remain as separate.

There is no “Combine Meshes” option I have seen on older posts similar to this and “Joining” them in blender didnt seem to work either. I feel like this is a feel simple solution but my lack of experience is just missing it.

Any ideas?

EDIT: I found the combine meshes option! For some reason it only seems to show up when you use the “Import” option from the content drawer or its because I exported the fbx with only the mesh?

when you import there should be a combine meshes
