Is there a way to preview a message attachment from the Sidebar plugin, for example using the plugin SDK downloadAttachment()?

I am currently only getting a File object returned from Front.downloadAttachment('msg_xxx', 'fil_xxx') with the following properties:

size:  293622
type:  "image/jpeg"
webkitRelativePath: ""

This opens an attachment in a new window/tab.

Front.downloadAttachment(message.id, attachment.id)
  .then(blob => {
    const fileURL = URL.createObjectURL(blob);
    window.open(fileURL, '_blank'); // Opens in a new tab
  })
  .catch(error => {
    console.error('Error fetching attachment:', error);
  });

That SDK method is what you’ll want to use. It delivers the raw attachment content, so you can present it using whatever method you like as a preview. 

Front does not currently provide any built-in tooling to render a file preview, so you can use whatever tool you’re already familiar with to render your preview.
