Install issue

[Clement-TS]

While starting the install script, is get a typeError cannot use property getId of null, line 81:

var doc_id = DocumentApp.getActiveDocument().getId();

same. guess development on this project must not be super active

It seems getActiveDocument() has been removed from the Drive API. I tried to circumvent this issue by copying the doc_id manually from the doc url, but creating the dropdown menu failed: i got the same error when trying to use the getUI() method.

Illegal character. (line 879, file "Code") << how to fix this?
