Hello JANARDH Y,
Thanks for your question.
Reach out to your Databricks workspace administrator to verify and adjust your permissions.
If its you or them, In the Azure Databricks workspace, click on the username in the top bar and select admin console and select advanced then permissions. In the token permissions editor, search for your user account or group and assign the CAN USE permission, which allows you to create and use PATs.
