How to use “rclone copy” via sftp with remote sudo?

I am using the “rclone copy” command to copy a folder from a remote sftp host to my computer. The remote user that I am using doesn’t have privileges to read every single file inside that folder. Formerly, I was using rsync with the parameter --rsync-path="sudo rsync" to bypass that problem, but I don’t know what the equivalent would be under rclone.
