How to access ppg sensors of SAMSUNG watches?

Question

Tizen

For my application, designed for Samsung watches on Tizen, I need to use a PPG sensor and get raw data from it. I found how to use it: tizen.sensorservice.getDefaultSensor("HRM_RAW"). However, getDefaultSensor("HRM_RAW") requires access to one of the led sensors to work. I check their availability on my Galaxy Watch active 2:
tizen.systeminfo.getCapability(" tizen.org/feature/sensor.heart_rate_monitor.led_green ")
tizen.systeminfo.getCapability(" tizen.org/feature/sensor.heart_rate_monitor.led_ir " )
tizen.systeminfo.getCapability(" tizen.org/feature/sensor.heart_rate_monitor.led_red ")
and find that they are not available. Although I added them to Feature in config.xml. Can I access them on my device, and if not, how can I find out on which devices I can get this access?
