Currently, I have developed an Office add-in using AngularJS (version 1.4) and ASP.NET MVC 4.5. The Angular controller and service JS files contain a significant amount of functionality that has already been implemented.
Lately, I have been exploring the use of Office ribbon buttons and commands (JS API version 1.3). My goal is to access JavaScript functions located in my Angular files (such as $scope or service) from these ribbon buttons. What would be the most effective approach to achieve this integration?
