My nodejs request doesnt work, what am i missing?

I am writting a Node.js console application that , receives an excel sheet, gets the values of a column, then with those values i call a Google Maps Geocode request to get the Latitude and Longitude, save it and add new columns to the excel sheet.

I have those two archives

const ExcelJS = require('exceljs');

// Ler o Excel existente e pegar os ceps

const wb = new ExcelJS.Workbook();

const fileName = 'NovoExcel.xlsx';

var ceps = [];


wb.xlsx.readFile(fileName).then(() => {
    
    const ws = wb.getWorksheet('Planilha1');

    const c1 = ws.getColumn(1);
    
    c1.eachCell(c => {

        ceps.push(c.value);
    });

    console.log(ceps);

    var mapsFunc =require("./maps")

    var coordenadas = mapsFunc(ceps);

    console.log(coordenadas)


}).catch(err => {
    console.log(err.message);
});

Thats the other archive which calls the Api

const {Client} = require("@googlemaps/google-maps-services-js");
var maps = function(ceps){
  
var Latitude = [];
var Longitude = [];

ceps.forEach(element => {
    

const args = {
  params: {
    key: 'AIzaSyA5_Hox6vhpLt3kRpqxr_0eXBUssHIva7g',
    address: element + ' br ',
  }
};
const client = new Client();
client.geocode(args).then(gcResponse => {
  Latitude.push(gcResponse.data.results[0].geometry.location.lat)
  Longitude.push(gcResponse.data.results[0].geometry.location.lng)
  console.log(Latitude)
});

});

return [Latitude,Longitude]

}

module.exports = maps;

I dont understand why it calls the console.log thats the answer of the function i call before it calls the actual function, what am i missing?
