Using Phased Array System Toolbox to estimate DOA with Tetrahedral Array

I'm using tetrahedral microphone array structure to estimate location of a sound source. Very similar example of the design can be seen in the image:

I'm able to receive 4 channel signal via USB. Now I am struggling to find proper resources to use object of DOA for Arbitrary Array Geometries for my purpose. I'm open to any resource/guide/code.
