Showing or Launching a pdf attached in Dataverse

[AUG_Anja]

Hi together, 

I try to show a pdf in the pdf viewer, which is attached in Dataverse. But neither the AbsoluteUri nor the Value shows me the pdf in the viewer. A alternative would be lauching the pdf via browser, but when I try "Launch(ThisItem.AbsoluteUri)", the I get a new tab with "letter salad". How can I get the right URL for the attached pdf for showing or lauching the attachment?

Thanks,

Anja

Ok, after a new setup of the gallery I can use the pdf-viewer. But I don't have only pictures or pdfs for showing. I have attachments like Excel or Emails too. After a search in the internet it seems that a direct launch is not possible because of the decoding  into a base64 string format. But I need a possibility to show or launch other formats. 

Is there a possibility to show Emails (stored in the attachments from Dataverse) or Excel-/Word-Files?

Or it's possible to launch the attachments (and encode them)?
