Where to add user to the vboxuser group / USB passthrough /Ubuntu HA VM on Win10

I am following the instruction on how to get USB passthrough for my zwave stick from the win vm into HA. I keep seeing notes to add the user running virtual box to the vboxusers group. In windows there is no vboxuser group created. Im not sure where to check what groups exist on the HA box. When I open HA I get the Home Assistant CLI. I tried to run the command (sudo usermod -aG vboxusers <USERNAME>) on the HA CLI refrenced on these sites but Im getting unknown command. Can someone tell me what I am missing? Thanks in advance.

I’m using HAOS in VirtualBox on Windows 10. Didn’t have to setup any user groups.

You need to create a USB filter to pass the stick to HA. (Make sure you turn off all energy control settings for the stick in windows) (in device manager).
