title: Give proxy SQL access to Google Colaboratory
body: <p>I'm trying to connect my Google Colaboratory Notebook to the Google Cloud SQL Instance I have, but I can't. My instance is only accessed with Cloud SQL Proxy, and I have no whitelisted any ip. What would be the steps to connect to it? I have also tried to download cloud_proxy_sql, but the problem is I can't give it execution permissions to the file...</p>
  
  <p>Do you have any suggestion about this?</p>
