go to qb-core/config.lua and replace this section QBConfig.Notify.VariantDefinitions with mine below

QBConfig.Notify.VariantDefinitions = {
    success = {
        classes = 'success',
        icon = 'task_alt'
    },
    primary = {
        classes = 'primary',
        icon = 'notifications'
    },
    error = {
        classes = 'error',
        icon = 'warning'
    },
    police = {
        classes = 'police',
        icon = 'local_police'
    },
    ambulance = {
        classes = 'ambulance',
        icon = 'fas fa-ambulance'
    },
    stress = {
        classes = 'stress',
        icon = 'psychology'
    },
    sms = {
        classes = 'sms',
        icon = 'chat_bubble'
    },
    bank = {
        classes = 'bank',
        icon = 'account_balance'
    },
    hunger = {
        classes = 'hunger',
        icon = 'lunch_dining'
    },
    thirst = {
        classes = 'thirst',
        icon = 'water_full'
    },
    email = {
        classes = 'email',
        icon = 'mail'
    },
    warning = {
        classes = 'warning',
        icon = 'warning'
    },
    announcement = {
        classes = 'announcement',
        icon = 'campaign'
    },
}

Done now just incorporate your new notification types into your existing scripts

Heres an example of adding the stress type in qb-hud

qb-hud/server.lua

RegisterNetEvent('hud:server:GainStress', function(amount)
    if Config.DisableStress then return end
    local src = source
    local Player = QBCore.Functions.GetPlayer(src)
    local Job = Player.PlayerData.job.name
    local JobType = Player.PlayerData.job.type
    local newStress
    if not Player or Config.WhitelistedJobs[JobType] or Config.WhitelistedJobs[Job] then return end
    if not ResetStress then
        if not Player.PlayerData.metadata['stress'] then
            Player.PlayerData.metadata['stress'] = 0
        end
        newStress = Player.PlayerData.metadata['stress'] + amount
        if newStress <= 0 then newStress = 0 end
    else
        newStress = 0
    end
    if newStress > 100 then
        newStress = 100
    end
    Player.Functions.SetMetaData('stress', newStress)
    TriggerClientEvent('hud:client:UpdateStress', src, newStress)
    TriggerClientEvent('QBCore:Notify', src, Lang:t("notify.stress_gain"), 'stress', 1500) -- Notice here i changed the type from error to stress
end)
