Apps interconenction

Hi, I am about ot buy smart trainer and i would like to ask how to get the most of it regarding the data and apps. Obviously, I will have to connect Strava to Zwift to get rides uploaded on strava. But then I have also garmin with HR sensor so I would like to ask if and how to connect also this to the system so also my HR is uploaded to the strava after my zwift ride. Thank you
