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

const getDocTemplates = async(userName) => {

    let user = getUser(userName);

    let docsAPI = new DocumentsAPI(new InfluxDB({url: __config.influx_url, token: user.token, timeout: 20000, }));

    return await docsAPI.getDocumentsTemplates({orgID: user.orgid});
};

const createTemplateFromFile = async(userName, filepath) => {

    let user = getUser(userName);

    let docsAPI = new DocumentsAPI(new InfluxDB({url: __config.influx_url, token: user.token, timeout: 20000}));


    let content = await readFileToBuffer(process.cwd() + '/' + filepath);
    let newTemplate = JSON.parse(content);
    newTemplate.orgID = user.orgid;

    docsAPI.postDocumentsTemplates({ body: newTemplate});
};
