usage with satty

[Khyretos]

the default editor of grimblast is gimp and i want to use it with satty
the command to run to edit an area for example is grimblast edit area - | satty -f -

but when i edit the qml file:

        {
          label: "All Screens",
          command: "grimblast",
          args: ["edit", "area", "-", "|", "satty", "-f", "-"]
        }

it does not do anything. it says it succesfully saved the screenshot but nothing happens, can you help me with this?
