A bit late, but may I ask where you got that? Silly but fun.
I was looking for my Panasonic 14mm 2.5 and finally found it on my Air which I have not used since my Nexus 5X days. Decided to find the old OA.Central app and install it on my backup phone (Pixel 4XL, so 4th phone I had since that Nexus). Took a bit of time to remember how to connect that little thing, but I got it working... I now remember how much fun that little thing was...

Also found this from apparently the last time I used it...
