The comment is wrong: the string placed there (archive icon next to Search in Archived Chats Folder) is "Archive" string (https://translations.telegram.org/stringnames/android/unsorted/Archive) and not this one - let's have a look at it with String Names custom language (https://translations.telegram.org/stringnames/). I don't know where this string is actually used.
This string will be available in the app in the upcoming 7.3 version
