Pairing Suunto Smart Sensor HR Monitor

Hi,
Setting up Zwift for first time and struggling to get my Suunto Smart Sensor HR Monitor to pair w/ Zwift. Using PC w/ Windows 10. HR monitor is fully charged and disconnected from all other devices. I can get it to pair with the PC via with Windows Bluetooth controller but it won’t connect to Zwift either when connected or disconnected to the PC via Windows.
Any suggestions as to how I can get it to connect?
Thanks
