Request: I want to set JIS eisu key as a modifier key

[kt0319]

local function keyCode(key, modifiers)
   modifiers = modifiers or {}
   return function()
      hs.eventtap.event.newKeyEvent(modifiers, string.lower(key), true):post()
      hs.timer.usleep(1000)
      hs.eventtap.event.newKeyEvent(modifiers, string.lower(key), false):post()
   end
end

local function remapKey(modifiers, key, keyCode)
   hs.hotkey.bind(modifiers, key, keyCode, nil, keyCode)
end

remapKey({'eisu'}, 'h', keyCode('left'))
remapKey({'eisu'}, 'j', keyCode('down'))
remapKey({'eisu'}, 'k', keyCode('up'))
remapKey({'eisu'}, 'l', keyCode('right'))

Although it is set like this, it is judged that it is pushed even if you release the eisu key.
Please be able to set eisu key etc as modifier key.

I'm not sure how macOS handles eisu, but I've never seen it referenced anywhere in Carbon as a modifier that can be used like ctrl/alt/shift/opt/cmd.

@asmagill any ideas here?
