Which fingerprint sensor does my cell phone have?

I'm currently writing a seminar paper on biometric authentication. I looked at the different fingerprint sensors yesterday and found that there are two different ones used in cell phones. The optical and the capacitive. In order to be able to carry out a self-experiment to circumvent the different methods later, I would like to know which sensor my cell phone has.
I have a Huawei mate 20 lite. Does anyone know which one uses this phone or how I can find out?

Usually appears on data sheets

Optical
