CodeM Supreme Chat

Its display name is built in an encrypted server/functions.lua from Config.PlayerName ('game' | 'fivem'), and its client exports (GetSettings, UpdateSettings, GetRestrictedChannels) are about settings, not names. Its built-in commands cannot be changed.

What can be done: chat:addMessage accepts showPlayerData = {id, name} for messages a resource sends itself. So any command you write can carry a different name for every recipient.

We do not ship or modify their code.

#A per-recipient /me through Supreme Chat

-- your own resource, server side
RegisterCommand('me', function(src, args)
    local text = table.concat(args, ' ')
    if text == '' then return end

    local origin = GetEntityCoords(GetPlayerPed(src))

    for _, id in ipairs(GetPlayers()) do
        local viewer = tonumber(id)
        if #(GetEntityCoords(GetPlayerPed(viewer)) - origin) <= 20.0 then
            local name = (viewer == src) and 'You'
                or exports['5code-recognition']:GetRecognitionLabel(viewer, src)
                or 'Stranger'

            TriggerClientEvent('chat:addMessage', viewer, {
                template = '<div class="chat-message me"><b>{0}</b> {1}</div>',
                args = { name, text },
                showPlayerData = { id = src, name = name },
            })
        end
    end
end, false)

Every listener gets their own name, so nobody sees a name their character has not earned.

#Masks

Supreme Chat tracks mask anonymity with its own server event, which its own client sends on every message:

codem-supreme-chat:server:UpdateMaskState(isWearingMask)

Do not fire that event from our bridge: it is a client-authored signal on their side and ours would be overwritten by their next message. If you want their mask state to follow our tiered face coverage, ask them to call exports['5code-recognition']:IsFaceHidden(source) on the server instead.

#What is not possible today

Built-in commands (/ooc, /twt, channels, …) render the name from their encrypted code. Until CodeM adds a hook, recognition-driven names are limited to messages your own resource sends.
