Why isn't my canvas showing?

I’ve created a Canvas to add an health bar for my game experience. I also created an Image inside the canvas but only the image is showing and without clear perception of the limits of the canvas I can’t place my health bar correctly.

The UI components are visible so I don’t know what the problem is.

I’ll attach some printscreens for you to see what I’m talking about


Try activating the Gizmos button:

Thank you! Good tip as I had never used that controller before, I was actually able to see it afterwards when I deleted my canvas and created a new one. I think the problem was an error with my canvas being inside another objet (in the hierarchy)
