title: List databases return no results
body: <p>I have a workspace with 2 databases shared with my integration, basically it works and I get 200 OK code.</p>
  <p>That's the function I have, the headers contain the authentication token:</p>
  <pre><code>def listDatabases(self):
      r = requests.get('https://api.notion.com/v1/databases', headers=self.headers)
      if r.status_code == 200:
          return r.json()
      else:
          return r.reason
  </code></pre>
  <p>And this is the result:</p>
