How to texture an imported FBX?

I created a complex organic shape in Maya which I’ve import into UE5 as an FBX. I’m having trouble applying UE5 textures to the shape.
What is a proper way to apply UE5 textures to an imported file (FBX) from Maya?

Thank you for your time. I look forward to your reply.

Kind regards,
Christopher

Did you UV the shape ( in Maya ) before importing?
