     // Wait for the download to start
     Download download = page.waitForDownload(() -> {
         // Perform the action that initiates download
         page.getByText("Download file").click();
     });
    
     // Wait for the download process to complete and save the downloaded file somewhere
     download.saveAs(Paths.get("/path/to/save/at/", download.suggestedFilename()));
