The conversion from CSV should result in an event log in your ProM workspace (leftmost tab at the top, next to the Action and View tabs). In this workspace, you can then select this event log and export it to a XES file.
Please note that in the workspace there is an event log, not a XES file per se. ProM plugins work mainly with in-memory objects, and not with files. Exceptions are the import plugins (to import an in-memory object from a file) and the export plugins (to export an in-memory object to a file.
