Like I said, there isn’t a direct path to adding editable fields to the dashboard using ACF. There are no hooks in WP that ACF can use to do this. You will need to create an options page or somewhere else to attach the ACF field group to. To put the fields on the dashboard you will need to create a dashboard widget https://codex.wordpress.org/Function_Reference/wp_add_dashboard_widget. In your dashboard widget you could probably use an acf_form() https://www.advancedcustomfields.com/resources/acf_form/
