here is my roles file but whenever I try /fly or /nickname it is not working

{
"default": {
"level": 1,
"overrides": {
"name_decoration": {
"style": ["yellow"],
"prefix": {"text": "Trainer ", "color": "yellow"}
},
"command_feedback": true,
"commands": {
"help": "allow",
".": "deny"
}
}
},
"donator": {
"level": 2,
"overrides": {
"name_decoration": {
"style": ["dark_blue"],
"prefix": {"text": "Donator ", "color": "dark_blue"}
},
"command_feedback": true,
"commands": {
"help": "allow",
"essentialcommands.home.set": "allow",
"essentialcommands.home.tp": "allow",
"essentialcommands.home.delete": "allow",
"essentialcommands.nickname.self": "allow"
}
}
},
"vip": {
"level": 3,
"includes": ["donator"],
"overrides": {
"name_decoration": {
"style": ["gold"],
"prefix": {"text": "V.I.P ", "color": "gold"}
},
"command_feedback": true,
"commands": {
"help": "allow",
"essentialcommands.": "allow"
}
}
},
"owner": {
"level": 4,
"overrides": {
"name_decoration": {
"style": ["red", "bold"],
"prefix": {"text": "Owner ", "color": "red"}
},
"permission_level": 4,
"command_feedback": true,
"commands": {
".": "allow"
}
}
},
"everyone": {
"overrides": {
"commands": {
"help": "allow",
".*": "deny"
}
}
}
}

Needed to use "permission_keys": { } and remove ".*": "deny" from default
