Embedding a Zoho Analytics view into Creator with user-based criteria

Embedding a Zoho Analytics view into Creator with user-based criteria

I have a Creator app where organisations can track projects for groups of young people.  I want to report back to them a nice set of stats about the impact of their projects and the young people's demographics, so I have created a dashboard in Zoho Analytics, and I have embedded it into a Zoho Creator page.

My current embed code is: https://analytics.zoho.eu/open-view/147073000000xxxxxx?ZOHO_CRITERIA=%22Projects%22.%22Facilitator%22%3D%24%7Bsystem.login.email%7D

However, the end users won't have a login to Zoho Analytics so I can't use these inbuilt Analytics user-based filters.

I have a Creator function called thisapp.GetMyProjects so I can provide the list of projects to include, but I don't know how to use that in a way that Analytics can interpret.  Does anyone know how I amend this filter please?
