Is it under assigned permissions or not?
could you post screenshots regarding it

Thx for the answer. The problem is that the permission is visible, but the app is not.

Our Integration name is avtexInsights and the permission required is Integration > avtexInsightsApps > View .

And could you please tell me how I can check this? I cannot see anywhere how the enable/disable a permission.
Do you perhpas mean puting permissions into a Role and then assigning that Role to a user?

It is not visible because the permission required related to your {premiumapp}integration -> view is not enabled.
If this permission is enabled then it will be visible

Hi Pawel_Kowalik,

Try clearing your browser cache if the app doesn't appear immediately
