Collection Service for GUIs?

In my game, I'm creating a lot of textbuttons with a localscript. I essentially want to be able to sense if any of them are clicked, and know which one. Right now I'm accomplishing this by inserting a localscript into every button, but I don't want that many scripts, preferably just one.

I know that there's collectionservice, but I tried using it and it didn't work. Here's my code:

--This is a localscript
local collectionService = game:GetService("CollectionService")

for _, gui in pairs(collectionService:GetTagged("Button")) do
    gui.MouseButton1Click:Connect(function()
        event:FireServer(gui.Name)
    end)
end

I'm not sure if it's possible to do this using collectionservice, and if it isn't how would you do this?

Any help would be appreciated :)
