Installing autossh as a service with cygwin?

Question

I am trying to install autossh as a service via cygwin:

cygrunsrv -I AutoSSH -p /usr/bin/autossh -a “-M 20000 -R 7000:10.xxx.xxx.193:22 jessica@host” -e AUTOSSH_NTSERVICE=yes

But I get the error:

cygrunsrv: Exactly one of --install, --remove, --start, --stop, --query, or --list is required
Try `cygrunsrv --help' for more information.
