How can I make it so if I type not the entire username it can find that player?

I'm trying to make this admin script and I'm trying to make it so I don't have to type the entire username so If I did typed "marioet77" full username it would work but if I typed "mario" then it wouldn't can you tell me how I could make this happen? Here's the code.

local remoteII = game.ReplicatedStorage.Remotezz

remoteII.OnServerInvoke = function(plr, CodeBox)
    local args = CodeBox:split(" ")
    if args[1] == "Tools" then
        for i,v in pairs(game.Players:GetPlayers()) do
            if v.Name:lower():match(args[2]:lower()) then
              function GetTools(a)
                if (a.className == "Tool") then
                  a:Clone().Parent = game.Players:FindFirstChild(args[2]).Backpack
                end
                local b = a:GetChildren()
                for i=1,#b do
                  GetTools(b[i])
                end
              end
            end

            GetTools(game.Players:FindFirstChild(args[2]).PlayerGui.Shh.Handle.Tools)
        end
    end
end
