Showing HA Calendar Weekly view on esp

I’ve a ePaper display with a esp connected to it. I know how I can get values from HA and display them. but is it also possible to show a visual from HA directly? Because afaik there’s no easy way to build the weekly shedule from the calendar widget manualy.
Anyone some idea how to proceed?

Quick Update: Thanks to How to list multiple calendar event in a template - #137 by tomik67 I get a list of all events from all calendars.
