[musaabimran]

Please check if the PR fulfills these requirements:

• Tests for the changes have been added/updated (if possible)
• Documentation has been updated/added if relevant
• Screenshots are attached to Github PR if visual/UI changes were made

What is the current behavior?

The student grader cannot see the results folder so the button "Open/Close Results" shouldn't be there.

What is the new behavior?

Now the button is not visible to the student grader. Closes #9570
