title: How to set SameSite=None for my Devise session cookie?
body: <p>I'm developing a Chrome Extension that works in conjunction with a rails backend. When users are logged into the backend site, I want to customize the extension UI according to their account. Normal stuff.</p>
  <p>Because this is a browser extension, the &quot;document&quot; / URL that requests to the backend will always be changing, so SameSite=None needs to be set.</p>
  <p>How can I customize the Devise cookie settings? Everything I found so far online shows me how to set cookie information globally via a rails config:</p>
  <pre><code>YourApp::Application.config.session_store :cookie_store, { key: '_xxxx_session', secure: secure_option }
  </code></pre>
  <p>But I think technically I don't need this for every cookie, just the session cookie. I guess I could be wrong though...</p>
  <p>Thoughts?</p>
