Client Members Tab

Client Members Tab

I am trying to provide my client with access to zoho to see scheduled content and reports - according to zoho help:  https://help.zoho.com/portal/kb/articles/how-do-i-invite-my-clients-to-my-brand-on-zoho-social
I should have a Client Member tab in my brand members and rolls page and I don't.  How am I supposed to add a client to their brand?
