I'm developing an Apps Script that has a sidebar and a dialog, each need differing levels of permissions to ask the user to be granted.
The application needs access to Read/Write the user's Google Drive API, Google Picker, access to Web Cam and Microphone, Web Speech API, and Google Docs API.
How can I get prompt the user once for all permissions needed, instead of having to force the user to launch open the sidebar and dialog once separatelu, each via the add-on menu?
