This took a long time to figure out myself. Finally I got it working

Open the octopi.txt config:
sudo nano /boot/octopi.txt

Look for the line:
#camera="auto"
Change it to:
camera="usb"

Then reboot:
sudo shutdown -r now

Open the Octoprint web interface, go into Octoprint Settings, and update the stream URL to (then test):
http://octopi.local/webcam/?action=stream

If that worked then update the snapshot URL to (and test):
http://octopi.local/webcam/?action=snapshot

If everything worked, then click save.

After a bit more time testing, this appears to work for a few minutes then stops working.

Changing the settings to:
camera="raspi"
and adding:
camera_raspi_options="-x 1640 -y 1232 -fps 15 -quality 85 -ex auto -awb auto"

Appear to work best.
