WinUI3 : How to put an translucent grey overlay on Canvas
I'm working on a WinUI3 desktop application in c++. I was trying to achieve an experience where we can show a ProgressRing in the center of the screen when there is a delay in screen update. In my application, my window has a Canvas as its content and that canvas contains many widgets. I want to put a new Canvas as an overlay on top of the existing Canvas and show a ProgressRing on the new Overlay Canvas and I was able to achieve an experience like this.
The overlay Canvas in the image has a background color as transparent, I wanted to make the overlay canvas translucent. So that all the widgets below the overlay canvas will look like grayed-out non-interactive widgets.
I would be of great help if you could help me with this issue.
Thank you,

One way to do that is to set the Background("Black" maybe?) and the Opacity depending on how you want it to look.
