How to retrieve embed image data from Microsoft Graph when there are no attachments?

I'm using Microsoft Graph to pull email data from a mailbox. When I get the content, I find embedded images with content like so:

<img id="_x0000_i1029" 
     width="1366" 
     height="672" 
     data-outlook-trace="F:1|T:1" 
     src="cid:[email protected]" 
     style="width:14.2291in; height:7.0in">

When the property hasAttachments is true, I look for images that match and replace the content and it works great. The problem is I see embedded image tags like this on messages where hasAttachments is false.

Where can I get the image data Graph says the Message has no attachments but there clearly are embedded images?

Note that the image renders in Outlook for the Web with a tag like:

<img data-imagetype="AttachmentByCid"        
     originalsrc="cid:[email protected]" 
     data-custom="AAMkADY1YjgxM2Y4LTE5NTUtNDBjMy1iZDY0LWIzN..." 
     naturalheight="672" 
     naturalwidth="1366" 
     src="https://attachments.office.net/owa/[email protected]/service.svc/s/GetAttachmentThumbnail?id=AAMkADY1YjgxM2Y4LTE5NTUtNDBjMy1iZDY0LWIzN...&amp;thumbnailType=2&amp;owa=outlook.office365.com&amp;scriptVer=2019031102.10&amp;X-OWA-CANARY=kKWSUkiFW0WjlPXXXXXXXXX.&amp;token=eyJhbGciOiJSU...&amp;animation=true" 
     id="_x0000_i1029" 
     data-outlook-trace="F:1|T:1" 
     style="width: 1024.49pt; height: 504pt; cursor: pointer;" 
     crossorigin="use-credentials" >

Using Microsoft Graph API you can get all attachments of a mail:

GET https://graph.microsoft.com/v1.0/me/messages/{id}/attachments

or

GET https://graph.microsoft.com/v1.0/users/{id | userPrincipalName}/messages/{id}/attachments

When you get all attachments you can check property isInline to find embedded images.

You can get attachments even if an email has property hasAttachments set to false, because that property is related to not inline attachments.
