Is that a Dexcom G7 sensor on Halsey’s (singer) arm?

Saw this picture of Halsey on her Facebook, it was a post for her son’s birthday, and I noticed she had something on the back of her left arm. It immediately looked like a sensor of some sort but not one I recognised, so I checked images of different typed of sensors and it looks to be a Dexcom G7, can anyone confirm this? I don’t have this exact sensor so I can’t be too sure. If she does have this, I’m surprised as she’s not diabetic, but she has a lot of other medical illnesses but I don’t think that means anything in terms of why she’s using a sensor.
