This blog post aims to create a Twilio Flex plugin that allows agents to virtually raise their hand to ask a supervisor for help. The plugin uses Twilio Sync to persist the state of the agent's hand in the cloud, enabling supervisors to monitor and respond to agent calls for help from a single place. The plugin is built using React and Twilio Flex's built-in SDKs, allowing developers to create a custom component that integrates with the existing Flex UI. The code demonstrates how to create a custom component, use Twilio Sync to persist state, and reuse the component in the supervisors overview screen. The post also touches on potential future features, such as using Flex Actions Framework to automate hand-raising when agents log in or out, or Flex Notifications Framework to grab the attention of supervisors when they are away from the Teams view.
