        {
            "Effect": "Allow",
               "Action": [
                "glue:UpdateTable",
                "glue:GetDatabase",
                "glue:GetDatabases",
                "glue:GetCatalog",
                "glue:GetCatalogs",
                "glue:GetPartitions",
                "glue:GetPartition",
                "glue:GetTable",
                "glue:GetTables"
            ],
            "Useful resource": [
                "arn:aws:glue:::table/icebergdemodb/*",
                "arn:aws:glue:::database/icebergdemodb",
                "arn:aws:glue:::catalog"
            ]
        },
        {
            "Impact": "Enable",
            "Motion": [
                "lakeformation:GetDataAccess"
