Profit at Risk

[EverFrost]

Hello friends, I received a warning to download an ads.txt file and upload it to the root domain of each site in order to avoid a significant decrease in your income. I am using Blogspot and had added ads.txt for blogspot.com, but now I am being asked to do the same for the German extension blogspot.de. How can I do this on Blogger? Is there anyone who knows the method? Thanks in advance for your help.
