Duplication of files in Beta?

In the non-Beta Adobe Express it's very easy to duplicate and rename a file (so that you kind of treat it like a template for your next similar image). Basically, you hover over the three dots and reveal a 'duplicate' option and then you rename the file. But I don't see how to duplicate a file in Adobe Beta. First of all, in Beta you have to open the actual file instead of having the 3 dots in the thumbnail view; and second of all, I see no duplication option in the Beta view.
