Hi Jeong Hoon Kim,
Thank you for reaching out to us on the Microsoft Q&A forum.
From the details you shared, it appears that regional restrictions may be affecting your ability to access the Power BI Service with your personal account.
To address this, we recommend reaching out to your admin or IT team to request a Power BI Pro license, which will grant you access to the Power BI Service. Once the license is assigned, you should be able to proceed with the module.
Alternatively, if feasible, you could ask a colleague with the required credentials to share their access with you to help you complete the module.
In the meantime, you can continue using Power BI Desktop, which is free and offers full functionality for creating dashboards and reports locally.
Please reach out to us if you have any other queries.
