Z-axis direction on Matrix

From https://matrix-io.github.io/matrix-documentation/matrix-hal/components/microphone/, we can know the direction of x and y axis, now just curious about the deirection of z-axis on MATRIX CREATER, is it points inside towards Matrix or point out?

In the datasheet available here https://www.element14.com/community/docs/DOC-87675/l/matrix-creator-datasheetpdf there is a reference to the X and Y axis in the Hardware Specification topic. the Z axis is going out of the board following the right hand rule.
