Open windows in the same group regardless of focus

[keliss]

Hi, so I want to open all Firefox windows on the second workspace as a single group, while all other windows should open ungrouped. I have the following config:

windowrulev2 = group barred, workspace:2
windowrulev2 = group override set, class:firefox

The problem with it is when I open a Firefox window and a terminal side by side, focus the terminal window, and then try to open another Firefox window, this window creates a new group instead of going to the group of the existing Firefox one. I couldn't find a way to solve this with the existing Hyprland config options. Any ideas?
