Do not see external Har drive

[Perk]

I am following a guide to install windows on external hard drive on my new 2018 mac mini using VMware fusion. When trying to export the win 10 iso file to the external usb drive. I am NOT able to see it in wintousb. The External hard drive is shown in win10 using VMware fusion and in my mac.
The only hard drive i am seeing in wintousb is the internal hard drive disk 1
I am not able to proceed without seeing my external hard drive in WINTOUSB

WinToUSB will only display the USB drives in the list box, it is not possible to display the internal disk, please reconfirm it.
