Admin review set participants

Hi, 

I am trying to use command line "ccollab admin review set-participants" but whatever I used I got an error "JSON API Error: Invalid User". I am trying to set multiple participants as reviewer and one participants as author. The first problem is how can I pass the name and last name for a user? I passed just a name and it gave an invalid user.

I tried all below cases:

ccollab admin review set-participants 98484 --participant reviewer=Albert

Please advice how can I use this command for the latest code collaborator version?
