File Approval process new file replace exiting one after approve


how does the approval app work? I can make a workflow and see than that the file is approved or rejected.

My preferred workflow is:

  1. ask for approve (with approval app)
  2. accepted / rejected (with approval app)
  3. existing file was replaced by the accepted file, before file get accepted, the old file was there.

step 3. I don’t know how to do.
