Pixel Watch 3 connect to spinning bike

I Have the Google Pixel Watch 3 and also have a Yesoul Spinning bike but can't get measure the power on my spinning exercises. I can use apps like Zwift/Training Peaks to track power meter but can't get that data on fitbit. I can connect GPW3 to Training Peaks and broadcast heartrate but how can I get that data on fitbit? Would be nice to have all that data, including sleep and all GPW3 tracks on the same app, like fitbit. So can I get the power meter data from my Yesoul soining bike on fitbit or GPW3?
