[xmonad] Removing border around gkrellm

[Michał Trybus]

Hi,
is there a way to remove the border around a particular window?
In particular, is there a way to use
XMonad.Actions.NoBorders.toggleBorder inside a managehook?
I'm bad at haskell and xmonad internals and have no idea how to wrap
toggleBorder to use inside of:
composeAll[
  resource =? "gkrellm" --> ...
]
I've been simply trying to have the same effect as M.fromList [((modm,
xK_g), withFocused toggleBorder)] does, but automatically.

Regards,
Michał Trybus
