an we bring back the first section of full width without going back to the first version of the page

[null null]

I have deleted a full width section of a newly created sharepoint communication site.

How do i get it back as the hero web part in the sections below are not full width.

Can we bring back the first section of full width without going back to the first version of the page.

Thanks

if we  go to the site settings and edit left navigation and remove all items, it gets automatically converted to full screen mode in modern view.
