Using plugin outlet to customise dashboard layout


I am really new to discourse and would like to edit the layout of my page’s dashboard. I would like to change the HTML of the dashboard to include the calendar for my page using the ‘discovery list container top’ plugin outlet. Since the calendar is located in another page, I was planning to use jquery to access the element by its id to be displayed on the dashboard.

From what i have read i believe i should be using the above code in the after header section of the built-in html editor, but I am not too sure where I should input the logic to display the calendar from the other page.

Any help will be greatly appreciated!
