Need to overlay heart rate and speed information from apple watch

I use manyCam to live stream sports activities to YouTube live using my iphone, I want to overlay realtime player info such as heart rate, speed, number of steps, EKG information from there Apple Watch, currently there are other apps that overlay information such as garmin Virb and ios app called Vido meter, but non of them support multi camera or LiveYoutube Streaming, how is apple watch overlay possible using manyCam?
