Where can I add new apps for exploit protection in the on-premise product?

I'm looking for guidance on how to add additional applications to my endgame policy threat | exploit configuration. The major browsers and office apps are there along with Java and Adobe, and I have the option to add applications, yet... there's no guidance on this. There's plenty of documentation on trusted applications, but not adding apps, like Visio or something else. I type in Visio in the Additional Applications and hit the PLUS icon to add it, and it appears, but I'm not sure it's working. Shouldn't I use Visio.exe or do I need to see these apps in other areas of the product.

I'm finding the Admin Guide and User Guide documentation to be a bit lacking on the general features.
