Can a trigger open the Resources tab

Just finally got this to work, because

The example uses forward slashes /, but it should be backslashes \.

You have to turn on the Resources tab in the player. It's not enough to just upload the pdf as a resource. If you look at your publish folder and there is no external files folder, that's why, because unless you turn on the tab, the pdf doesn't publish.

EDIT: I realized later that I could just fake the same outcome by using the folder created when I published with the Resource tab showing. (Probably could have even made it from scratch). So, I turned off the Resource tab, then added the pdf to the publish folder manually. So, I created the file link in the trigger that reads story_content\external_files\myPdfFile.pdf, then placed a folder in story_content called external_files, and inside that is my pdf. Works like a charm and no need to show the tab.

My LMS team reports that it works as expected in SABA.
