How to use the @influxdata/influxdb-client-apis.LabelsAPI function in @influxdata/influxdb-client-apis

const createLabel = async(userName,
    labelName,
    labelDescr,
    labelColor ) =>{

    let user = getUser(userName);

    const lblAPI = new LabelsAPI(new InfluxDB({url: __config.influx_url, token: user.token, timeout: 20000}));

    let lblCreateReq = {body: {name: labelName, orgID: user.orgid,
        properties: { description: labelDescr, color: labelColor }}};

    await lblAPI.postLabels(lblCreateReq).catch(async error => {
       console.log('--- Error Creating label ---');
       console.error(error);
       throw error;
    });
};
