How to add Date range filter in script reports?

I have a script report called Trip Report MIS. For this report I have multiple filters. One of them is Date Range. On this filter I want to let user select a range of data and based on that it should filter docs that were created within that range (I have a field ‘created_on’). How do i make this happen.
Here is my code

.js

frappe.query_reports["Trip Report MIS V2"] = {
	"filters": [
		{
			'fieldname': 'name',
			'label': __('Trip Id'),
			'fieldtype': 'Link',
			'options': 'Trips'
		},
		{
			'fieldname': 'lr_number',
			'label': __('LR Number'),
			'fieldtype': 'Data',
		},
		{
			'fieldname': 'vendor',
			'label': __('Vendor'),
			'fieldtype': 'Link',
			'options': 'Vendor'
		},
		{
			'fieldname': 'vehicle_number',
			'label': __('Vehicle Number'),
			'fieldtype': 'Link',
			'options': 'Vehicle'
		},
		{
			'fieldname': 'origin',
			'label': __('Source/Origin'),
			'fieldtype': 'Link',
			'options': 'Geofence'
		},
		{
			'fieldname': 'destination',
			'label': __('Destination'),
			'fieldtype': 'Link',
			'options': 'Geofence'
		},
		{
			'fieldname': 'driver_number',
			'label': __('Driver Number'),
			'fieldtype': 'Data'
		},
		{
			'fieldname': 'created_at',
			'label': 'Date Range',
			'fieldtype': 'Date'
		},
		{
			'fieldname': 'status',
			'label': __('Status'),
			'fieldtype': 'Select',
			'options': ['', 'Driver Consent Pending', 'Loading', 'Enroute to Destination', 'Unloading', 'Completed', 'Stopped', 'Completed & POD received'],
			'default': ''
		},
	]
};

try this for date range:

	"filters": [
		{
			"fieldname":"dob",
			"label": __("Enter Your Date Range"),
			"fieldtype": "Date Range",
		},	
	],

to set default values in the date range so follow the script in the JS file:

dobFrom = new Date();
dobFrom.setFullYear(dobFrom.getFullYear() - 50);
dobTo = new Date();
frappe.query_reports["My Script Report"] = {
	"filters": [
		{
			"fieldname":"dobRange",
			"label": __("Enter Your Date Range "),
			"fieldtype": "Date Range",
			"default": [dobFrom,dobTo]
		},
	],
