How to do a "save as" on embedded API report?

I'm able to embed a Power BI report in my app: 

<script>
    // Read embed application token from Model
    var accessToken = "@Model.EmbedToken.Token";

    // Read embed URL from Model
    var embedUrl = "@Html.Raw(Model.EmbedUrl)";

    // Read report Id from Model
    var embedReportId = "@Model.Id";

    // Get models. models contains enums that can be used.
    var models = window['powerbi-client'].models;

    // Embed configuration used to describe the what and how to embed.
    // This object is used when calling powerbi.embed.
    // This also includes settings and options such as filters.
    // You can find more information at https://github.com/Microsoft/PowerBI-JavaScript/wiki/Embed-Configuration-Details.
    var config = {
        type: 'report',
        tokenType: models.TokenType.Embed,
        accessToken: accessToken,
        embedUrl: embedUrl,
        id: embedReportId,
        permissions: models.Permissions.All,
        settings: {
            filterPaneEnabled: true,
            navContentPaneEnabled: true
        }
    };

    // Get a reference to the embedded report HTML element
    var reportContainer = $('#embedContainer')[0];

    // Embed the report and display it within the div container.
    var report = powerbi.embed(reportContainer, config);
</script>

I want to creata a "save as" button on the page with the embedded report to save a new copy of the report into the workspace, but I'm at a loss as to how to code the javascript in my cshtml.  

Does anyone have an example they'd be willing to share?
