"ReferenceError: WebSocket is not defined" when using createLongLivedTokenAuth

[Erik]

When I am trying to run the example code for using a long lived token, I get an error in socket.js:

Code:

const auth = createLongLivedTokenAuth(
    this.host,
    this.token
);

this.wsConnection = await createConnection({ auth });

Error:
