Solved Problem with permission for all players

Hi.

I am trying to add permission for all players on the server with this command :

grant group player bounty.use


In the console I can see : ( and it is not working )

(01:38:41) | [RCON][87.64.22.166:62099] grant group player bounty.use

(01:38:41) | [Oxide] 01:38 [Info] Group 'player' doesn't exist

Can you tell me what to do ? Normally, this group is a generic one no ?

 

Thx Wulf
