There is no documentation (I could find) about how to set up or access the Contact Dashboard page. CiviCRM has this permission "CiviCRM: access Contact Dashboard" - but finding what URL to use to view the Contact Dashboard page requires some serious Google Kung-Fuey!
Would be good to have in the User Guide this information, in it's own section I would say too.
There is this section, but I don't think it's relevant for this topic. https://docs.civicrm.org/user/en/latest/the-user-interface/menu-dashboard-and-dashlets/
Two methods: /civicrm/user Or from back-end, when viewing a Contact, use the Actions menu button to click on the Contact Dashboard item. URL looks something like: /wp-admin/admin.php?page=CiviCRM&q=civicrm%2Fuser&reset=1&id=62&cid=62
Permissions: Requires the user to be logged in and the assigned role needs to have the "CiviCRM: access Contact Dashboard" permission enabled. OR The use a Contact Checksum URL and the Anonymous role needs to have the "CiviCRM: access Contact Dashboard" permission enabled.
