Return checkHasApiPermission as a method that can be used by other dashboards-plugins

[cwperks]

Description

Companion OSD core PR: opensearch-project/OpenSearch-Dashboards#11620

Example usage in a dashboards-plugin (in this case reporting): cwperks/dashboards-reporting#2

This PR returns checkHasApiPermission from security-dashboards-plugin for use by other dashboards plugins to conditionally hide/reveal from the main menu. The intended consumer of this is a new dashboards-job-scheduler plugin.

Category

Enhancement

Issues Resolved

Related to opensearch-project/security#5635, but limited in scope to hiding/revealing a menu item only if the logged in user is a security admin.

Testing

See companion PRs:

1. Login as admin and see all menu items
2. Login as non-admin (i.e. readall:readall) and verify the menu items do not appear for plugins that use the updater and should only be displayed for admins
