App-ads.txt file

Question:
I would like to add an app-ads.txt file to my site, but I’m unsure of how to do that.

Product:
Wix Editor

What are you trying to achieve:
I would like to add an app-ads.txt file to my domain (example.com/app-ads.txt)

It’s not possible to add files at the root of a Wix website. Can you clarify the usecase here?
