Zoom F3 / MEMS microphone Recording sample of self-made microphone (ICS-40730)

Recording sample by combining Zoom F3 and my own MEMS microphone (ICS-40730).
I made my own MEMS microphone that matches the compact housing of the Zoom F3.
For information on my own microphone, I referred to "Shin's PA workshop".

What do you use your F3 for, are you an audio engineer or technician? Will point to side like this able to catch voice in front and behind the camera clearly, can add another shotgun mic facing Front and rear and the front and back sound clearer and become a 360 degree mics setup too? Can you use the USB C port as line in 3.5mm audio port with USB C mic and 3.5mm mic with adaptor?

I use the F3 as a hobbyist.　This DIY microphone is omni-directional, so it can record forward sound clearly.
A shotgun mic would be even better.
The USBC port can only be used as an audio interface.
