IModelApp Class
Global singleton that connects the user interface with the iTwin.js services. There can be only one IModelApp active in a session. All members of IModelApp are static, and it serves as a singleton object for gaining access to session information.
Before any interactive operations may be performed by the @itwin/core-frontend package, IModelApp.startup must be called and awaited.
Applications may customize the frontend behavior of iTwin.js by supplying options to IModelApp.startup.
