Embed.videodelivery.net has been reported as unsafe to Microsoft Defender

When browsing our website today we recieved this big scary warning from Microsoft Defender saying that the https://embed.videodelivery.net/embed/iframe.fla9.b06b8f1.html?videoId=4dce5e3ac90ecf68bebc88222400f19d have been reported as unsafe. This url obviously comes from the Cloudflare stream.

Is this something that we need to take up with Microsoft or is this a domain wide issue that Cloudflare need to take up with Microsoft?

This is obviously not a good look for any of our users coming to our website that have microsoft defender installed.
