Recently i am trying to rewrite my whole config file in lua, i want to open some apps on other work space without focusing that workspace , so i created a bunch of window rule named w1 - w10…
and it only works as intended for kitty, while other apps like spicetify (–class not found) and google-chrome-stable (–class ‘w3’ just open a new tab with the url w3/)

here is my window rule code:

for i=1,10 do
  local work=tostring(i);
  hl.window_rule({
    match={
      class="w"..work
    },
    workspace=work.." silent"
  })
end

That’s how browsers do things.
They run a daemon that grabs any new instance of a program at does w/e it wants with it. Nothing the compositor can do about that.

is there any way to apply a class to an app? i dont want to apply window rule to that specific app’s class, bc i want to make a keybind that open apps in other workspace without focusing it.
