@91557984 Welcome to Microsoft Q&A Forum, Thank you for posting your query here!
Please note that the content safety APIs/studio need Cognitive Services User
role to be assigned.
Action Plan:
- Please check with the Subscription Owner to grant the "Cognitive Service User" RBAC role on the resource level for your user account.
- Then wait for 30 minutes for the role to propagate.
- Then clear the browser cache and access again.
Hope this helps. If you have any follow-up questions, please let me know. I would be happy to help.
