Issues Inserting Video Embed Codes into Storyline

I'm trying to insert an embed code from Open Text Media Management into a Storyline file, using the Video > Video from Website option. However, I receive the error message "A video cannot be inserted from this embed code.
Verify that the embed code is correct and then try again."

The embed code from OTMM is generated in the following format. Note: Our instance is only available internally so I removed the specific link & ID as it won't be visible to others and for security purposes. 

<otmm-setup session-headers='{"X-OTMM-Widget" : "true"}'></otmm-setup><script src=https://{OUR-INSTANCE.COM}/otmm/ux-html/dist/otmm-platform.min.js></script> <link rel="import" href=https://{OUR-INSTANCE.COM}/otmm/ux-html/dist/otmm-widget-base.min.html> <link rel="import" href=https://{OUR-INSTANCE.COM}/otmm/ux-html/dist/asset-inspector.min.html> <otmm-asset-inspector id="otmm-widget" style="width:100%;height:400px;" asset-id="{ALPHANUMERIC-ID}" asset-type="video"></otmm-asset-inspector>

When I've embedded from other resources, the embed codes used <iframe> tags and I'm not familiar with the format originating out of OTMM. Does anyone know if this type of embed code can be used?

Thanks!
