How can I fetch table data using node-rfc SAP's BAPI

Question

I need to fetch table data from a SAP system with node-rfc library. Need help where I can pass table name or parameters so that I can get proper data to build Node.js API.

Do you have any idea what is wrong? I'm out of ideas :(

const noderfc = require("node-rfc");

const client = new noderfc.Client({ dest: "MME" });

(async () => {
  try {
    // unlike the connection acquired from pool,
    // the direct client connection is initially closed
    await client.open();

    // invoke ABAP function module, passing structure and table parameters

    // ABAP structure
    const abap_structure = {
      RFCINT4: 345,
      RFCFLOAT: 1.23456789,
      RFCCHAR4: "ABCD",
      RFCDATE: "20180625", // ABAP date format
      // or RFCDATE: new Date('2018-06-25'), // as JavaScript Date object, with clientOption "date"
    };
    // ABAP table
    let abap_table = [abap_structure];

    const result = await client.call("STFC_STRUCTURE", {
      IMPORTSTRUCT: abap_structure,
      RFCTABLE: abap_table,
    });

    // check the result
    console.log(result);
    GetDataTableFromRFCTable(result.RFCTABLE);
  } catch (err) {
    // connection and invocation errors
    console.error(err);
  }
})();

// Assuming DataTable, GetDataTableFromRFCTable, etc., are defined elsewhere
function GetDataTableFromRFCTable(lrfcTable) {
  console.log("lrfcTable", lrfcTable);
  
}

Response I am getting like.
