What are the screen sensors on my iPad Pro 2020

I have added a paper texture screen protector to my iPad Pro 12.9, there are cutouts for the camera and sensors. Where I have not perfectly aligned the protector the cutouts very slightly obscure the 2 outer most sensors and (if you are looking at the sensors with them at the top of the screen) the left sensor in the middle row of 5 sensors/mic. I cannot find anywhere online that specifies what these other sensors are. Face recognition is working fine but I’m concerned clipping the edge of the others will effect functionality.
