How to make blur frame in ui?

i saw people made posts how to make blur frame using module 3D in ui but i dont understand how can anyone help?

thank you for reading !!

Add BlurEffect in camera and adjust blur with size, when ready put this code in a Local Script in StarterPlayerScripts.

local Blur = Instance.new("BlurEffect",workspace.Camera)
Blur.Size =   --|Previous size

no i want a menu that have blur on it a frame in GUI in a part of screen

Just an specific part must be blurred? might be with a special image that is almost transparent, or maybe some property I don’t know

Sorry but it can not.

Sadly you cant do this easily (yet?)
There used to be a trick to use a semi-transparent black neon part in the camera, at the position of the Gui. Not sure if that works still
