How can I export a chart/graph created in google earth engine?

Question

I want to export a chart created in gee to a png format, but I don't know if that's possible. This is my code, I wanna export an NDVI over time chart.

var startDate = '2022-01-01'
var endDate = '2022-12-04'

var roi= ee.Geometry.Point([-50,-30])

var l8 = ee.ImageCollection('LANDSAT/LC08/C02/T1_L2')
.filterBounds(roi)
.filterDate(startDate, endDate)

// Map a function over the Landsat 8 TOA collection to add an NDVI band.
var withNDVI = l8.map(function(image) {
  var ndvi = image.normalizedDifference(['SR_B5', 'SR_B4']).rename('NDVI');
  return image.addBands(ndvi);
});

// Create a chart.
var chart = ui.Chart.image.series({
  imageCollection: withNDVI.select('NDVI'),
  region: roi,
  reducer: ee.Reducer.first(),
  scale: 30
}).setOptions({title: 'NDVI over time'});
