How to generate the heart beats while using ecg 3 click (MAX30003) and STM32F446E board?

I have been able to get the library of the chip used in ecg 3 Click ( MAX30003) but now, my challenge is the function to use to generate or read the heart beats. I can’t see it from the library , Can somebody help please ?

NB : I’m using STM32F446E as microcontroller .
