These tokens are used by the frontend application to connect to the created room and subscribe for room updates. The article covers setting up environment variables, dependencies, and creating functions for generating tokens, validating room names, and connecting to rooms using Twilio Video. It also guides the reader through configuring Rollup for bundling the frontend application successfully.
