🧩 Problem statement
When a user with inadequate permission to run manual jobs in a project gets to the graph, this is what they see:
There is no clear communication as to why they couldn't perform this action and what should be the next step for them(e.g. reach out to a person with the permission to run this job).
Communicate to users with limited permissions why they cannot run manual jobs and the next steps they could follow.
- Show a disabled action button
- Show a tooltip explaining the lacking permissions
