You can subscribe to platform events with the empApi component in your Lightning web component.The empApi component provides access to methods for subscribing to a streaming channel and listening to event messages.
The empApi component uses a shared CometD-based Streaming API connection, enabling you to run multiple streaming apps in the browser for one user. The connection is not shared across user sessions.
To use the empApi methods in your Lightning web component, import the methods from the lightning/empApi module as follows.
You will find a perfect code example here to try with:
