UI button on image target won't show

Hey, I’m trying to have an UI button appear on an image target.
I placed the canvas with the ui button into the image-target. The image target is recognized but the UI button won’t appear.

I double checked by placing a 3D model into the image target instead and it worked.
UI elements in general won’t show.

Am I doing anthing wrong here?

Thx in advance!

You can fix this by doing these steps. You need to add the “Canvas Scaler” component to the canvas, set the UI Scale Mode on the component to “scale with screen size”

Your actual canvas should be set to Render Mode: screen space overlay.

Now drag the anchors apart so they fit around your element, with enough space so the image can resize on different devices.
