Sending Error Message on Failed Install

Hi all,

I want to ask if we listen for the app installed event for connect app (using ACE), is there a way to send error message to be displayed (if there’s an error). For example, if the user is trying to install the app, but for whatever reason cannot, can we display custom error message instead of the generic: “The app host returned HTTP response code 401 when we tried to contact it during installation.”?
