How to use the @microsoft/signalr/dist/esm/HttpConnection.HttpConnection function in @microsoft/signalr

it("can connect to the server without specifying transport explicitly", (done) => {
        const message = "Hello World!";
        const connection = new HttpConnection(ECHOENDPOINT_URL, {
            ...commonOptions,
        });

        connection.onreceive = async (data: any) => {
            if (data === message) {
                connection.stop();
            }
        };

        connection.onclose = (error: any) => {
            expect(error).toBeUndefined();
            done();
        };

        connection.start(TransferFormat.Text).then(() => {
            connection.send(message);
