            Hi! 👋 We're experimenting with a new feature called debugger.
          </div>
          <div>
            This debugger allows you to see the state of your workflow in a live
            browser.
          </div>
          <div>
            You can run individual blocks, instead of the whole workflow.
          </div>
          <div>
            To get started, press the play button on a block in your workflow.
          </div>
        </div>
