Image creation using Hyper-V manager - Cannot mount physical USB to make bootable

Hi,

Here is the scenario
I have set up Hyper-V in my Windows 11 and then created a new Windows 11 VM using it.

I have 1 partition in the VM and did the image creation which told me to make a USB as the first step.
It was impossible to add a physical USB to Hyper-V VM.
Does somebody know how this can work?

Thanks in advance.
