* You must have **Admin** or **Build** permission on the semantic model.
* Semantic models in Direct Lake mode require additional configuration [mentioned here](https://docs.fabricplan.com/planning-sheets/how-tos/create-and-share-a-cloud-connection-for-a-semantic-model#connect-to-a-direct-lake-semantic-model).
