Vaadin - Select file button

Hello, I’m new to vaadin, I’m looking for a button to select file.
I do not know if the Upload component is the right one, since I do not want it to go anywhere, but the only thing I need is the name of the file that the user selected.
I’ve been looking for several days and the only thing I get are suggestions to upload and regrettably is not what I need.

Thank you very much!
Enrique.
