what do i type for oxide.grant group so all players can use teleportation ive been typing this in
oxide.grant group teleportation that doesn’t work 

you have to type
/oxide.grant group default nteleportation.home - /home, /sethome, /removehome
/oxide.grant group default nteleportation.deletehome - /home delete & /deletehome
/oxide.grant group default nteleportation.tpb - /tpb = returns you to last location teleported from,
/oxide.grant group default nteleportation.tpr - /tpr  = allows you to send requests to tp to other players,
 /oxide.grant group default nteleportation.tpa - /tpa  = allows you to accept tp requests from other players,

These are the most used permissions, there are more listed in the permissions section of the documentation, but be wary of what permissions you grant players

That makes sense ty
