how do i remove a woo-commerce widget?

The message is suggesting you can hide this area by going into the admin backend customizer.

You can find these setting in the customizer by going to Admin > Appearance > Customize.

Once you have the customizer open the exact setting will depend on your theme. It may be nested under the WooCommerce tab or another tab created by your theme. Just poke around and look for a way to change the “Store Page” layout to “Full Width”.
