How to make text and icon (button) in one line at different css corners?

Question

css

Good afternoon.
I started making a custom file uploader, but as a result I ran into such a problem that I couldn’t display the bottom information about the files.
codepen
That is, it should be inside the uploader form, but all files uploaded in this form, through v-for, etc. will be displayed as a separate block.


I would be grateful for your help, or maybe you can point me to the links where to see what should be used in this case.
