I see I have forgotten something when extracting code to a more generic
example: making an instance of the class...
So the corrected version:

      class MyClass
        def props
          some_data = SomeClass::get_prop
          some_data.to_h
        end
        def props[key]=(value)       # Not a valid construct
          SomeClass::set_prop(key, value)
        end
      end

      my_instance = MyClass.new
      my_instance.props["timeout"]
      =>"10"

      my_instance.props["timeout"]="20"
      => nil
