hi @sqren,
We talk about what will happen if licenseManagement.locator is undefined, but I'm actually not sure if we want to fall back to the licensePageUrl = '/app/management/stack/license_management'
what else we can do in this case? any suggestions?

In the case where license management plugin is disabled we don't want to link to the license page, because it'll display a 404. In that case I think we can just not show the link.
That being said, I don't think this will ever happen. If the license management is not enabled, the user ought to have something like an enterprise license, with access to everything.
