Can anyone make a script that turns the player's character into a custom model on a button click?

Remember, it is not proper on scriptinghelpers to ask for scripts. Many cocky, toxic people who like to push this say "its scripting helpers not scripting givers!111 do you expect us to just GIVE you scripts lol!11!" But just don't post a question like this again. I wouldn't have answered this if I didn't already have a script.

script.Parent.ClickDetector.MouseClick:Connect(function(plr)
	local character = game.ServerStorage.Bear:Clone() -- Bear does not need to be in serverstorage. Put it where you need it, and rename as such.
	character.Name = plr.Name
	plr.Character = character
	character.Parent = workspace
end)

If you're talking about a Gui button:

script.Parent.MouseButton1Click:Connect(function(player)
	local character = game.ServerStorage.Bear:Clone() -- Bear does not need to be in serverstorage. Put it where you need it, and rename as such.
	character.Name = player.Name
	player.Character = character
	character.Parent = workspace
end)

These must be in server scripts, or the blue scroll without the little man popping out. The character will respawn but they will get the outfit. PLEASE check out youtubers like AlvinBlox they will help you SO MUCH with beginning AND advanced scripting. Please do not ask for scripts on this site.
