inline images in channel message not accessible

[jessekps]

I have created a message in teams. In the message I pasted an image from the clipboard. In teams the message looks fine. When I access the message in R I see an image in the source:

msg = channel$list_messages()[[1]]

cat(msg$properties$content$body)

>  <div><span><img height="250" src="https://graph.microsoft.com/beta/teams/fe42c.....

but I cannot download this image. If I paste the msg$webUrl in the browser, I get redirected to teams and it looks ok, so I obviously have access I would think. However, when I copy the url of the image in the browser I get the following response:

{"error":{"code":"InvalidAuthenticationToken","message":"Access token is empty.",
   "innerError":{"date":"2023-06-06T07:52:24",
   "request-id":"db016e7...","client-request-id":"db016e7..."}}}

Is this a bug or is there some other way to access this image outside of teams?

Nothing to do with R, or with this package. This is about how the server sets the content-type of the returned data.
