Obtain notification


I have made a notification widget for whenever an Item is picked but I am trying to add those little details that makes stuff look good.
I was trying to make some nice effect around the widget or making the widget it self shinny in order to to make it look good.
I have seen something similar in a video I was watching here

at that sec, The player took an item from the ground and a blending in and out animation obviously showed but i was surprised that it was not only shinning, laser from top right to left and bottom left to rigth as well. not mentioning that the icon was glowing and some kind of pulse was also there.
does anyone have any idea how this was made ? My assumption is that it might be a material and multipile widgets inside one but I am not quite sure.

Thank you
