Hi, we are using version 16 and would like to add legal terms on checkout (simple acceptance box) before customer confirms order. It surprises us something like this doesn't come out of the box (or we're just not looking good enough to find it). 

This is the module we found that could possibly solve our problem, but in version 16 there is no Customize menu on websites https://apps.odoo.com/apps/modules/16.0/website_sale_require_legal/

Did someone make it work on v16, or does anyone have any other idea how to add this feature on checkout? Thanks in advance.
