Deleted Admin Header

I mistakenly deleted the default admin header that comes with canvas, is there a way to get it back?

Hello! Welcome to the forum!

Did you delete the actual reusable element called header?

For all else this section of the documentation should help:

No, on the canvas editor, I navigated to the header and footer section, and deleted the header that is to be displayed when an admin is accesses the app

You are showing a header named admin on your screenshot.

What was deleted then?
