Can't create variable: collection of process objects

OS: win10
UIPath version: studio pro 2020.10.9 enterprise

I’m following a UIPath example to loop through open processes:

In step 2 it says to create a var:

Variable name: identifyProcesses
Variable type: System.Collections.ObjectModel.Collection<System.Diagnostics.Process>

I cannot figure out how to create the var type in uipath. When I click the variable type drop down and browse for types, systems.collections.objectmodel.collection is not found.


The easiest way is to press Ctrl +k, then input variable name at Processes property of GetProcesses activity. It automatically make variable as proper type.


Not able to found too:
