Get call to download a PDF file not working

I'm having a very similar problem to this one Download a file from API but with a PDF file. I've tried very similar solutions to the ones proposed on this issue, but none worked. If I use Postman my request is processed correctly, and I can download and open the PDF, but in Retool the response is wrapped in a JSON and something changes, so that the PDF file is corrupted.

Hey @Marcos_Rodriguez! Are you just using a GET request to a URL that holds the PDF file? Happen to have a test url that I can work with on my end. Getting a pretty standard base64Binary response with what I've been able to test so far. Thanks!
