I'm trying to connect Zapier to Zoho Creator, but can't get it to authenticate.

Zapier is asking for an auth token (which I have successfully created) and my "Ownername" or "screenname".  The instructions (here:  https://zapier.com/help/zoho-creator/) says that this can be obtained through the "My Workspaces" menu item below my profile icon at the top-right of the Zoho screen.  However that "My Workspaces" menu is not present for me.

I've tried using the "Full Name" used in my Zoho profile (which is the same as my Nick Name).  Also my email address, and my User ID.  None of these work.  I get the following error:  authorization failed: Specified ownername is not valid. Provide a correct one.

What should I be entering in this field?

Thanks
