6 demo BO, even so I couldn't scroll down to bottom of the side menu to access the module. This is due to by default the menu would not scroll, so you're able to't look at the links in direction of the bottom. There is a totally free module available to https://www.presta-addons-modules.com/en/front-office/prestashop-seo-webmaster-site-verification-for-search-engines.html
