Google earth engine real time data

Question

i am new to google earth engine.
I have a program for Atmosphere Monitoring. I have managed to pull data for historical data. However , i can't pull recent data e.g. (a couple of days, today , yesterday etc.) , i get ' memory limit exceeded.' or (Collection.toList: The value of 'count' must be positive. Got: 0.)
As it says 'Near-Real-Time' that mean that the data must update many times a day? My final goal is to be able to pull data in (near) real time so that I can this data through some other program visualize it. Is that possible?
Any advice will be helpful!
Thanks in advance!

var pt = ee.Geometry.Point(23.72801716860135,37.984115295446216);

Map.centerObject(pt,14);
Map.addLayer(pt);

var starDate = '2023-02-09';
var endDate = '2023-02-10';

var data = ee.ImageCollection('ECMWF/CAMS/NRT').select('total_aerosol_optical_depth_at_550nm_surface')
  .filterDate(starDate, endDate);

print(data);

var allDates = ee.List(data.aggregate_array('system:time_start'));

var allDatesSimple = allDates.map(function(date){
  return ee.Date(date).format().slice(0,10);
  });

//print(allDatesSimple);

var getTemp = function(image) {

  // Reducing region and getting value
  var value_tmmx = ee.Image(image)
    .reduceRegion(ee.Reducer.first(), pt)
    .get('total_aerosol_optical_depth_at_550nm_surface');
  return ee.Number(value_tmmx).multiply(0.1);

};

var count = data.size();

var tmmx_list = data.toList(count).map(getTemp);

print("tmmn_list", tmmx_list);

var paired = allDatesSimple.zip(tmmx_list);

print ("paired", paired);

var myFeatures = ee.FeatureCollection(paired.map(function(el){
  el = ee.List(el); // cast every element of the list
  return ee.Feature(null, {
    'date': ee.String(el.get(0)),
    'aerosol':ee.Number(el.get(1)),


  });
}));

print(myFeatures);

// Export features, specifying corresponding names.
Export.table.toDrive(myFeatures,
"export_aerosol", //my task
"GEE_Folder", //my export folder
"aerosol2",  //file name
"CSV");
