selenium - download file to /tmp not there - selenium

Question

When I download a file in Ubuntu to /tmp using selenium, the file doesn't appear. However, the count postfix of the filename keeps increasing in Chrome, e.g. file (1).txt - meaning the browser finds the previously downloaded files.
Example App.java:
public class App
{
public static void main( String[] args ) throws InterruptedException {
final ChromeOptions options = new ChromeOptions();
options.setExperimentalOption("prefs", Map.of("download.default_directory", "/tmp/"));
final ChromeDriver driver = new ChromeDriver(options);
driver.get("file:///home/.../download.html");
Thread.sleep(5000);
driver.quit();
}
}
download.html
<div>Hello</div>
<script>
const element = document.createElement('a');
element.setAttribute('href', 'data:text/plain;charset=utf-8,' + encodeURIComponent("Hello World"));
element.setAttribute('download', "file.txt");
element.style.display = 'none';
document.body.appendChild(element);
element.click();
document.body.removeChild(element);
</script>
After running this java code, the file cannot be found in /tmp or anywhere else in the filesystem: find . 2>/dev/null -name file.txt yields nothing. However, while the code is running, selenium keeps increasing the postfix of the filename:
Where is the downloaded file?

I guess the files are downloaded into your /home/username/Downloads folder, not to /tmp folder as you expecting.
