how do i add a equip system to my script?

local replicatedStorage = game:GetService("ReplicatedStorage")
local shopItems = game:GetService("ServerStorage"):WaitForChild("ShopItems") -- Where tools are held


replicatedStorage.GetInfo.OnServerInvoke = function(player,item)
    return shopItems[item].Points.Value
end


replicatedStorage.CheckSale.OnServerInvoke = function(player,item)
    
    local price = shopItems[item].Points.Value
    
    if player.leaderstats.Cash.Value >= price then
        
        player.leaderstats.Cash.Value = player.leaderstats.Cash.Value - price
        
        local gear = shopItems[item][item]:Clone()
        gear.Parent = player.StarterGear
        
        local gear = shopItems[item][item]:Clone()
        gear.Parent = player.Backpack
        
        return true
        
    else
        
        return false    
    
    end

    
    
end

how would I add an owned feature so when you buy it doesn't need to be purchased again and has a text equip/equipped?
