.htaccess Accessing a virtual directory and returning files from a real one?

Question

htaccess

The question is actually this:
Is there a file structure

• assets/app/name/
  
• assets/app/name2/
  
• assets/app/name3/
  

And calls of the form:
assets/FILENAME, and
so it is necessary that when accessing assets/FILENAME it returns, for example, assets/app/name/FILENAME

Answer 1

write in .htaccess: RewriteRule ^/assets/(.*)$ /assets/app/name/$1 [L]
and if there are no following lines, then write before the above line:

RewriteEngine On
RewriteBase /
