I am creating a PowerPoint Office-Js addin solution that depends on a native MacOS app running on the same system, which can be launched using a custom URL scheme (e.g. MyApp://doSpecificAction).
When I try to open that URL in a browser on MacOs, I get a confirmation prompt then the native app opens successfully. When I try to open the same URL from within the add-in, it doesn't work. Are there certain permissions that I need, and how to do that?
