Append additional information from fields to Calendar View

Hi all. Hope you are doing well.

I have added a Calendar view for Delivery Trip doctype as shown below.

I would like to add additional information in this view, that is to add Vehicle and Customer name. The delivery trip scheduling is done based on the sales orders. This will allow easier delivery trip scheduling with a clear view of the delivery time, driver, vehicle as well as customer.

How can I add these fields into the view? I am using this get_events_method: "frappe.desk.calendar.get_events".

Appreciate anyone’s kind assistance. Thank you.
