I have three questions, tell me please.

【As a premise】
--------------

I have a Google Apps Script project to do these.

 - Tweet automatically on my Twitter bot
 - Send mail from the my Gmail address
 - Read and write files on my Google Drive

I received an email with the following content from Google Apps Developers ([email protected]).

> Hi Google API Developer,

----------
Follow the instructions in this mail, open Google Cloud Platform, open the [Credentials] > [OAuth Agreement] screen and press [Send for Confirmation], the following error message appears. "[Application home page] link and [Application privacy policy] are required."

----------

【Question 1】
------------

Currently, I do not have a site corresponding to [application home page] and [application privacy policy]. Does it mean that the project of Google Apps Script stops unless I create it?

【Question 2】
------------

If I must create it, how can I create it? Are there any services that can make this possible on Google Drive?

【Question 3】
------------

If I can created a site, how do I associate it with Google Apps Script?

----------

I'm afraid that these might be basic, but could you tell me about these questions. 

Thank you and best regards.
