Control of powered zoom adapter PZ-E2B from EOS Utility

[DroneMan]

Summary question: Can the PZ-E2B powered zoom adapter be remotely controlled from within Canon's EOS Utility software?

I have the RF 24-105mm f/2.8 L IS USM Z lens on my R6 Mark II body and just received the PZ-E2B powered zoom adapter. I'm having trouble finding how to operate the powered zoom from within Canon EOS Utility. According to the product page (https://www.usa.canon.com/shop/p/power-zoom-adapter-pz-e2b), the powered zoom can be controlled within EOS Utility, but I'm not finding out how to do this. I can control other settings like focus, white balance, and exposure from EOS Utility just fine, but I'm seeing no option for powered zoom like I had expected. I'm using what I believe to be the latest version of the Utility software (3.18.40.9).

I need to be able to remotely control the zoom for an upcoming program. Has anyone else been able to do this from EOS Utility? There seems to be very few people using the powered zoom adapter, or at least I'm finding very little documentation for it online.

Here's the relevant section in the EOS Utility manual...

Looking at the text it appears that not all the cameras support the power zoom function remotely. It mentions EOS R5 and EOS R3 only.

That's unfortunate, @p4pictures, but thanks for digging that up. The product page certainly seems to be misleading to have the "Compatible EOS camera models only" asterisk on the part about assigning custom buttons but not on controlling via Canon EOS Utility. That seems to imply that any EOS camera can control it. Good catch from the manual.

So, at this point I think my only options are either returning the PZ-E2B adapter OR getting the zoom grip and finding some way to hardwire the two over distance. Do you know if there happens to be a long (20+ feet) cable that is compatible with the PZ-E2B adapter and ZSG-C10 zoom grip?
