How to access old versions of files

Maybe I’m pretty blind, but after searching for a while I could not find a way to access older versions of files in the user interface. Only when I use the fiel explorer on my Ubuntu server I find the files in the corresponding directory. Is there any other way using the UI?

Thank you all!

Ricght click at the 3 dots on the right, select info and when the new menu opens to the right, go to the tab versions.
When there are any (sometimes not), you can restore (circle arrow) or download (down arrow) an older version

Wow, that was fast!
Thank you very much, Hartmut!
