Thanks for reaching Microsoft Q&A Team.
To access blob data in the Azure portal with Microsoft Entra credentials, a user must have the following role assignments:
· A data access role, such as Storage Blob Data Contributor or Storage Blob Data Reader
· The Azure Resource Manager Reader role, at a minimum
Please add your account in the "Storage Blob Data Contributor" permission, allow 15 minutes for the changes to take effect, and then generate a user delegation key.
Please refer below articles for more information.
Hope this helps. Please let us know if you have any further questions and we will be glad to assist you further. Thank you!
