How do I find the UniveralType above another UniversalType?

Use the field "parent".

Use the field "parent" to request the UniversalType which is above in the hierarchy. You can stack "parent" into "parent" to work your way up in the hierarchy..

UniversalTypes have for levels.

query utsAboveOther {
  utsearch(code: "ST05-COLO") {
    content {
      code
      parent {
        code
      }
    }
  }
}
