It turns out that, similar to embedding base64-encoded sound files, you can pretty much embed any file you want to allow your user to download into your prototype.

(Note: if you’re viewing this on mobile, the embedded PDF may or may not work depending on your browser. Desktop should work well across the board)
You will still need to base64-encode your file as in the post linked above. Once you’ve done that (I used a zip file for this example), you can put this code into an “open external link” action:
javascript:
{
var uri = `data:application/zip;base64,[[YOUR BASE64-ENCODED FILE HERE]]`;
var name = "embedded-download.zip";
var link = document.createElement("a");
link.download = name;
link.href = uri;
link.style.display = "none";
document.body.appendChild(link);
link.click();
document.body.removeChild(link);
delete link;
window.close();
}
In my example RP file, I just put the entire base64-encoded file where I have [[YOUR BASE64-ENCODED FILE HERE]], but you can also store it in a variable or in a hidden widget, which would be appropriate if you want to have multiple download buttons in your prototype.
You will need to change the MIME type (application/zip in my above example) to match the type of file you’re embedding. You can see a list of common MIME types here.
Change the file name (embedded-download.zip in the example) to whatever name you want.
I’ve also included an example of an embedded PDF displayed in an inline frame, which is considerably simpler: just set the frame target as the data URI (the string that looks like data:application/pdf;base64,BASE64-ENCODED-PDF-GOES-HERE)
That’s it!
