How on Earth do I turn two partitions back into one?

I have an external drive that I split into two partitions.

I now want it back as one.

No amount of clicking, looking through Disk Utility's "help" or Googling is offering me any real-world, helpful advice.

I'm on High Sierra.

Without wishing to exper8ment on my disks, have you tried deleting the partitions? And then repartioning the drive?
How can I do that? There's no option to delete the partition.

Clicking on a partition and selecting "Erase" just offers to reformat (I still have two partitions).

On the partition map, selecting a partition means the "-" is greyed out, so I can't remove it.

I can't select a partition and increase it to 2TB (full HDD size) without deleting one, but I can't seemingly delete one.

What happened to the good ol' instruction manual...?
