How do you get the current Stryd power value for a data field?

Hi all, I'd like to include the current power value from my Stryd footpod in a data field I'm writing. I see at least three other developers in the app store have achieved this, and I was wondering if anyone could explain how? The Activity.Info class has a currentPower property, but I assume that's the Garmin power value, not the one from Stryd?
