Dexcom G6 apple Watch Middle Complication

Hi. I have an Apple Watch 7. Live in Australia. On the latest version of IOS. Seems like it’s not an option to add Dexcom G6 as a middle complication - only the smaller top left or bottom complications. Is there a trick to it because I’ve seen pictures where other people have. Maybe it’s a geographic limitation??

I believe you are correct. I use Sugarmate as my middle complication.

Sugarmate hijacks the calendar so yes you can put it in the middle
