Can't set permissions on files on Cloud drive

I am trying to set permissions on a WD Cloud drive and give myself “Full Control”. I keep getting errors saying I am not authorized to do this.
I am using Windows 10
I am logged in as Administrator
This is on my home network

Please help
Dave

You set the My Cloud User/Share permissions through the Dashboard > Share page via your web browser not through Windows File Explorer.

See the Dashboard Help or the My Cloud User Manual for more information on how to set Share permissions.

Thanks
