Hello,
You do not need to put “the_content” in any place.
If you want to be able to edit the shop archive page using Elementor you need to use Elementor Pro, the default Elementor does not have such option.
Go to Theme Options > WooCommerce > Shop > Shop page layout > choose position of the sidebar. Under WooCommerce section you can find also many other options to edit layout of the shop page, products effects etc.
To change this content – https://gyazo.com/fd5b546928fa0eb6545defdda9937690 , go to Static blocks > edit “Shop banner” using Elementor
