How to do a function when player is holding down mouse?

I am making a script that when the player holds down their left mouse button, it tweens a gui and they can interact with it, and when they release the left mouse button, the gui disappears. The problem I am having is if I hold the left mouse button and release too fast, the gui just stays on the screen instead of disappearing.

This is my code:

local player = game.Players.LocalPlayer
local mouse = player:GetMouse()

local circle = script.Parent.DummyCircle

mouse.Button1Down:connect(function()
    circle:TweenSize(UDim2.new(0,250,0,250),1,4,0.7)
end)

mouse.Button1Up:connect(function()
    wait(0.01)
    circle:TweenSize(UDim2.new(0,0,0,0),1,4,0.7)
end)

Here is a video of what happens
