Can always 3d print (or buy) a base that the UmC cradle (also a separate print/purchase) can sit on to hold it proud of the wall at a similar elevation to the socket and then either clip the flexible cable back or leave it hanging.If you're looking to be neat and tidy and wish to mount the UMC to the wall I'd suggest the longer cable (90cm on the link I provided US$95), or $230 on evchargers.com.au because as you can see from mine (30cm) it won't reach the wall with a protruding 5 pin socket. I don't mind mine just hanging there but each to their own.

That is correct.
A pole mount stirrup might work too, or print something similar
Or extend the cable (get a sparky to do it)
Or, I did see one install where they recessed the socket enclosure into the wall so that the socket plate was just proud of the wall, which gave the UMC enough angle on the dangle to be held in the cradle.
The only bad thing I noticed with that was that, ergonomically it was a PITA to install and awkward to unhook the socket and UMC to put in the boot. But I think it was a semipermanent installation (or ended up being) in the end
I am waaaaay too lazy when I use the umc in the shed and it looks like yours
