Using with Kits by MEvent

I just want to trigger the flag or /flag command for Warmode PVP as a KIT (using MEVENTS Kits)

  I have tried flag  and /flag and chat.say "/flag" and a couple other things but no dice... 

I can run warmode.setplayer %steamid% pve ( or PvP) 

but doing it this way I need a PVP kit and a PVE Kit which causes some issues. It runs commands as system.  I have admin and can run /flag or in F1 Console just type flag and it works but for some reason running as a chat command doesn't work or if I try flag %steamid% probably because flag is not a system command but more of a player command?

Thanks for any help. 

Also I am looking for a way to flag inactive players with PVP after x amount of days....
