I would like to install this plugin for VIP users, but that they can only in an 1 hour spawn 1 minicopter. How do I do this, how to edit config file?

{
"AssetPrefab": "assets/content/vehicles/minicopter/minicopter.entity.prefab",
"CanSpawnBuildingBlocked": false,
"MaxSpawnDistance": 5.0,
"PermissionCooldowns": {
"spawnmini.tier1": 86400.0, -- You want to change one of these to 3600 and then assign them that permission
"spawnmini.tier2": 43200.0,
"spawnmini.tier3": 21600.0
},
"SpawnHealth": 750.0,
"UnlimitedFuel": false
