very similar to how the relay is setup it simply doesnt use a relay bot
so ill try think of the basic
well do the settings in settings so relay is on and type is DB
this has the same check as other relay modes which is to check the other bots permission to use !gcr command, do set the other bots as leader to each other etc (this was including to so u can do the relay how u want eg i know an org that relays to 1 other org but the other org relay to about 4 other orgs)
remember all the bots need to be on same DB
