This can be achieved by handling its onAdd, onRemove, onProgress, and onStatusChange events. These events contain the `affectedFiles` which shows the list of affected files, and the `newState` which contains all the files. In addition, you should set a state variable to the `newState` and pass it to the files prop.
This will allow you to access all the uploaded files through this state variable:
