Grafana canvas with dynamic background by query field

Hello,

I have a canvas where I use an image as background (from an url). I want to dynamically change the image when the user logs in, based on a query field.
I tried to use the “Field” option but the image does not render. Only the Fixed parameter works.
Is this a limitation?
If so, is there an workaround?

I tried all kinds of ways to show an image but not working for me either.
