Generic Objects are not displayed in the Instances view

[uejo]

1. Describe the issue you are having and what you expected to happen.
   When clicking on the "Instances" on my Service details page i get redirected to the Service (All Generic Objects) page, but it doesn't show any generic objects, instead a blank page:
   

I expect the generic objects to get listed, same as in the Service UI:

2. Describe the steps to reproduce, including any log snippets and stack traces that will help diagnose.
   Create a service, and add a generic object to it. Click on the "Instances" Link in the Service details page.
   Note: this link is somehow only available as administrator, which is also differing from the Service UI, there you can see the generic object as a user with less privileges, i could also not really find out which permission is the correct one to enable the link.
   No errors in the the manageiq log, nor in the browser.

3. Describe your environment, including
   Version: container version from docker hub: quinteros-1.20240402225756_f6add08
   and
   radjabov-pre.20240404134108_e4479a1

I also stumbled upon this issue #8675
it might relate, although it doesn't note anything about the also missing permissions.
