Problems with Classify Document Scope activity output

Hello, I am very new to uipath and I have problems with the type of variable that I should use for the Classify Document Scope activity to which I have created a variable type contracts.results.classificationresult but I have not had a positive result without understanding what type of variable it is according to the message.

You can create variables using the hot keys Ctrl + K (place the cursor in the field for which you create the variable)

For the “Classify Docement Scope” activity, the variable type will be an array of the built-in uipath type Uipath.DocementProcessing.Contracts.Results.ClassificationResult
