Powershell command to grant reviewer rights to shared calendar

Hello Experts - I'm trying to figure out a powershell command that will grant reviewer permissions to a conference room calendar (which is setup as a resource) for a specific group of users.  I've done this on individual user accounts using the following but get an error with this account:

Add-MailboxFolderPermission "Media Conference":\calendar -AccessRight reviewer -User "Media Office"

I get the error:  A positional parameter cannot be found that accepts argument :\calendar

I'm guessing this is because the object is a resource but I'm not sure, can anyone help with the syntax?

Try using the email address instead of "Media Conference"   example  mediaconference@contoso.com:\calendar
