**What are your suggestions?**
I can't find the dataset being used in the example. A link to them would be great

Open sagemaker-featurestore/sagemaker_featurestore_fraud_detection_python_sdk.ipynb and inspect the cells that load or reference the dataset. Trace the dataset source used by the example, then add links where readers can find it and verify that the notebook still presents the dataset references clearly.
