Hiding Report Level filters in the Iframe

I'm attempting to show a PBI dashboard (from a .pbix file on SharePoint Online) within a Dynamics 365 on-line CRM iFrame.

1. I setup the allow embedded PBI dashboards in CRM settings.

2. I've added SharePoint and CRM to the IE Trusted sites.

3. I've tested dozens of SharePoint generated (and custom) URLs in the iFrame with "&action=embedview" argument.

I can get working URLs that attempt to download the .pbix file from SharePoint so the basic access works.  The challenge is getting the dashboard content to display within the iFrame instead of downloading the file.

Here is an example: https://xxx.sharepoint.com/Power%20BI/Projects.pbix&action=embedview

What am I missing?
