Mounting Arlo Pro 4 on a square, metal light pole

[Syversen]

I'm trying to mount an Arlo Pro 4 on a 12" diameter tennis court metal light pole. I can't screw into it, and none of the existing after market accessories seem capable of going around a square pole that's 12" in total diameter (3" per side).

I tried calling Home Depot and sat on hold for 10 minutes before the attendant suggested giving up and trying again some other time. Scrolled Amazon and Google for a while and didn't see anything. This seems like a solvable problem but I'm not seeing the solution, figured I'd ask the smart folks on here!

Help!

Maybe something like this? https://www.amazon.com/Universal-Mounting-Bracket-Essential-Koroao/dp/B08L7DWWJN

The largest strap should be about 24" (7.87" diameter), so it should be long enough.  

You will need to bring it down to charge it.  Also, the PIR sensor range is about 20-25".
