About the parameters of channel activity detection (cad)

In sx126x.c, SX126xSetCadParams is proposed to set the parameters. However, the meaning of cadDetPeak and cadDetMin is not well explained. The datasheet of semtech only gives a vague explanation about the “sensitivity”.
In https://semtech.my.salesforce.com/sfc/p/#E0000000JelG/a/2R000000Q1ES/SPexo9njbhEQLcJVUg1i0Su8p3tpAtwX1jhMBGlXsQI, semtech evaluates how to select the best parameters in CAD, but it doesn’t give a clear explanation.
So What’s the real function and meaning of those two parameters? what’s the unit of them, SNR? or others?

Hello,

I’m pretty sure that I answered you about this elsewhere in the past, do you confirm ?

Yes, you answered me in github, we submitted this topic in this forum again. We just want to receive more ideas from various developers. Thanks for your help!
