Current Behavior:
When users who do not have edit permissions (specifically, no access to the data source) attempt to click "Edit Chart" or "Create New Chart," the interface allows them to click, but nothing happens. There is no feedback or message indicating why the action cannot be completed.

Suggested Enhancement:
When a user without the necessary permissions attempts to edit or create a chart, display a clear message such as:
"You do not have the necessary permissions to edit or create charts. Please contact your administrator if you need access."
