title: Is it possible to install a Google App Script to a Google Sheet programatically through an API?
body: <p>I'm developing a webapp in which a user gives consent to my app (using oauth2) to edit/create Google Sheets programatically. This works okay.</p>
  
  <p>In the same way, I want to be able to install (through the API) an App Script (with the user's consent) in that same sheet. Is this possible? </p>
  
  <p>Background: I want this App Script to notify my webapp of any changes to said spreadsheet.</p>
