How do I hide filter pane when report embedded in model-driven app?

I have followed the instructions in Microsoft's Embed a Power BI report on a form and have embeded my report with contextual filtering.  The filter pane shows on the right side and I would like it hidden.  How do I do that?  The screenshot shown by Microsoft does not seem to have a filter pane displayed:

My report is created in Power BI Desktop and published to Power BI Service.  The following filter-related settings in Report Settings are off (not checked): "Allow users to change filter types" and "Enable search for the filter pane"

I also tried adding displaySettings->isHiddenInViewMode=true to the <PowerBIFilter> parameter (see below), which loads without error but the filter pane is still displayed in my model-driven app.

<parameters>
<PowerBIGroupId>XXXXX</PowerBIGroupId>
<PowerBIReportId>YYYYY</PowerBIReportId>
<TileUrl>https://app.powerbi.com/reportEmbed?reportId=YYYYY</TileUrl>
<PowerBIFilter>{"Filter": "[{\"$schema\":\"basic\",
\"target\":{\"table\":\"Customers\",\"column\":\"Account\"},
\"operator\":\"In\",\"values\":[$a],
\"filterType\":1,
\"displaySettings?\":{\"isHiddenInViewMode?\":true}}]", 
"Alias": {"$a": "name"}}</PowerBIFilter>
</parameters>

Is there a way to hide the filter pane when embedding a power bi report using this technique?  Any suggestion for a better way to accomplish this?

Thank you,

Lyn
