How to override polkit password prompt in pamac?

Alright, I have a working solution.

I add /etc/polkit-1/rules.d/99-pamac-override.rules with this contents:

polkit.addRule(function(action, subject) {
    if (action.id == "org.manjaro.pamac.commit" && subject.isInGroup("butla")) {
        return polkit.Result.YES;
    }
})

When I add the file polkitd reloads the rules, which can be observed when running systemctl status polkit.service.
