How to use the @microsoft/signalr/dist/browser/signalr.js.HubConnectionBuilder function in @microsoft/signalr

componentDidMount() {
    console.log('[signalR] starting');

    const url = `${window.Radarr.urlBase}/signalr/messages`;

    this.connection = new signalR.HubConnectionBuilder()
      .configureLogging(new Logger(signalR.LogLevel.Information))
      .withUrl(`${url}?access_token=${window.Radarr.apiKey}`)
      .withAutomaticReconnect({
        nextRetryDelayInMilliseconds: (retryContext) => {
          if (retryContext.elapsedMilliseconds > 180000) {
            this.props.dispatchSetAppValue({ isDisconnected: true });
          }
          return Math.min(retryContext.previousRetryCount, 10) * 1000;
        }
      })
      .build();

    this.connection.onreconnecting(this.onReconnecting);
    this.connection.onreconnected(this.onReconnected);
    this.connection.onclose(this.onClose);
