Summary
Follow-up to #100905 and #101005
We need to ensure that restricted access to Uptime (and UX) through RBAC is reflected in the navigation. E.g. a Space has limited access to the apps, should not show the sections in the navigation but reflect the same as in the main Kibana menu where the Uptime and/or UX is not available as an option.
This is documented in the component docs https://github.com/elastic/kibana/tree/master/x-pack/plugins/observability/public/components/shared/page_template
