Thunderbolt 3 (USB-C) to Apple Thunderbolt cable

My iMac has a Thunderbolt 3 (USB-C) port, which is a small oval shape.

My accessory device has an Apple Thunderbolt port, which is a larger rectangle shape.

Both ports are Thunderbolt 3, but each has a different port shape.

Is there a cable or adapter to connect these two things?

Never mind... that Apple Thunderbolt Cable is Thunderbolt 2/Thunderbolt.

I thought my accessory device was Thunderbolt 3 but it's not.
