How to change/delete file from fileuploader?

Help Apps

In my app I have FileUploader and everything works fine except there is not a possibility to change the file without refreshing the page.
I saw a video which said that there should be automaticly a bin “emoji” with the FileUploader but they thought there might be a bug why it was not showing for them either.
Is there any solution to this problem?
