You may set property prefix.group.name=MS_ and use transformation below:

      {
        "sourcePath": "$.displayName",
        "targetPath": "$.displayName",
        "functions": [
          {
            "condition": "'%prefix.group.name%' !== 'null'",
            "function": "concatString",
            "prefix": "%prefix.group.name%"
          }
        ]
      },
