title: Does bolt-python take care of returning 302 to a slack URL for an app's direct install URL
body: <p>When filling in details for my Slack app, I get <code>Your application's redirect URL must return a status code of 302 to a slack.com url</code> error on the direct install URL field (using the install URL <code>https://my-api-domain/slack/install</code> for the app):</p>

  <p>I'm wondering if <code>bolt-python</code> takes care of this case or is this something that a developer needs to take care of themselves? And is this direct URL necessary for my Slack app?</p>
