Embed pdf from Web-URL

What I’m trying to do

Hello everyone,
I have a problem embedding pdf files from an URL from the internet.

Things I have tried

So far I have found it via a link with the ! tried before. Unfortunately, I then see the link with a broken symbol, but not the PDF file.
Specifically, it’s about this URL:

![Use fire extinguishers correctly](https://publikationen.dguv.de/widgets/pdf/download/article/3110)

Sure, I could download it and then display it, but my goal was actually to just link to it and still be able to read it. This would save me a lot of data on my hard drive.
I would be very grateful for your help.
Best regards
