How can i pass id with email address in Power BI Embedded App owns Data

[Anonymous]

Hi Experts,

I'm working on a Power BI Embedded App owns data. I have a multi-tenant web application.

I've implemented the RLS logic to show logged in user's respective data on the web by using USERPRINCIPALNAME( ) DAX.

Now my new requirement is to implement Document Id logic. Let me explain.

I've tables 

1. Users (User Id, Email, Document Id)
2. Fact Table ( FactId, userId, Document id

A user has many document Ids.

Now if user 1 clicks on document 1 then only respective user 1 and respective document 1 data should be shown.

To handle user-related data I'm applying for Roles on Users table like Email = USERPRINCIPALNAME(). But it's showing me all document data which is wrong, it should only show document 1 data.

Here my question and requirement are how can I pass document id to apply a filter on the dataset to load only User1 and document1 data.

Here is JSON that I'm passing through.

{
  "accessLevel": "View",
  "allowSaveAs": "false",
  "identities": [
    {
      "username": "test@gmail.com",
      "roles": [
        "UserRole"
      ],
      "datasets": [
        "xxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxx"
      ]
    }
  ]
}

 Thanks
