Unable to copy usd file from one folder to other with in nucleus

Hi there,

i am trying to copy the USD file from one folder in nucleus to other folder in nucleus like
cp omniverse:///Users/aerial/assets/example.usd omniverse:///Users/aerial/plateau/example.usd

I am, getting error on executing the file copy command.
cp: cannot stat ‘omniverse:///Users/aerial/assets/template.usd’: No such file or directory

Please suggest any code with in omniverse extension which will help in copying the file from folder to other with in nucleus.
