How to use ConditionType

I am trying to create a object using

TestObject RowToBeClicked = new TestObject().addProperty(“xpath”, ConditionType.EQUALS, “//tr[${RowTobe}]/td[1]”)

RowToBe is a variable but I am getting an error for conditionType as below

Reason:

groovy.lang.MissingPropertyException: No such property: ConditionType for class: Script1605804838566

import com.kms.katalon.core.testobject.ConditionType
