How to access common/assets?

Hi,

Have a question. I am working with an advanced template for my project. In my common/assets folder I created a folder called flags. I added all flag images in there that I use. However, when I want to access them in the backend of my application I can not get them to load. A simple path to /common/assets/flags doesn’t work.

How can I access the files I stored in the common/assets/flags folder?

Thanks.

Files to be accessed should be either located under webroot or be published via asset bundles.
