How do I hide or block access to the robots.txt file and the sitemap.xml file?

Question

How do I prevent access to my sitemap and robots.txt file?

There are those who can access the file of the robots.txt and sitemap by typing on browser the following:

https://mysite.com/sitmap.xml

https://mysite.com/robots.txt

I want to prevent these files from appearing to any other user

Both files are public instructions for search engines. Hiding them would be counter-productive. Also, why would you even care? Is there an actual problem you're trying to solve?

No, it's not a problem at all
But some sites when you search for it do not appear

Some sites may not have those files. They're not a requirement, just good practice.
