Just try formatting it again, perhaps there is some fluke that requires you to "erase" your existing partition before you succeed to format APFS.
Well, weirdly, I did format the drive as APFS to begin with. I mean that's what I chose in the options. I did it right, but it turned into something else. I did it several times and it would never let me "partition" it, nor did it give the dialogue box for adding a new APFS volume.

When erasing / formatting I chose APFS and GUID partition map. That's consistent with the internal disk.

This has me annoyed and / or amused, so I'm actually going to erase the drive and do it again to see if I missed something.
