Prevent a window from taking focus or switching workspace

[constantitus]

Description

I'm trying to prevent a window, specifically Steam, from taking focus when it opens.
I've tried the following

windowrule = workspace 10, ^(steam)$
windowrule = noinitialfocus, ^(steam)$
windowrule = suppressevent activatefocus, ^(steam)$

Now it opens windows on workspace 10, but they still switch my view to workspace 10, which I don't want.
Can I force it to spawn silently without taking focus or switching workspace ?

If this is not possible, then it's a feature request.
Thanks

you can use windowrulev2

like

windowrulev2 = workspace 8 silent, class:^(.*discord)$

Thanks, that did the trick. I should have read the whole wiki page on Window Rules, the silent parameter was hidden in there
