We'll create fresh WordPress site with Manage Privacy Options Page installed. You have 20 minutes to test the plugin after that site we'll be deleted.
Add roles that can edit the privacy page. That’s it.
Remember that a Data Protection Officer (DPO) should be administrator and/or have access to the settings in order to do its job correctly.
But also, you may need to add other roles allowed to edit the privacy page, this is why this plugin exists.
