Winium Automation in Java. How can I press the letters in my keyboard like letter "Y"?

Here's the list of commands that I've tried but still it didn't work.

    driver.findElement(By.name("3")).sendKeys("Y");
    driver.findElement(By.name("3")).sendKeys(Keys.CONTROL+"\u0059");

    driver.findElement(By.name("3")).sendKeys(Keys.CONTROL+"Y");


    driver.findElement(By.name("3")).sendKeys(String.valueOf('\u0059'));
    driver.findElement(By.name("3")).sendKeys(Keys.CONTROL + "Y" + Keys.CONTROL);
    driver.findElement(By.name("3")).sendKeys(Keys.CONTROL).sendkeys();




  driver.keyDown(Keys.CONTROL).sendKeys(String.valueOf('\u0061')).perform();

    String selectAll = Keys.chord(Keys.CONTROL, "Y");
    driver.findElement(By.name("3")).sendKeys(selectAll);
    driver.findElement(By.name("3")).sendKeys(Keys.chord(Keys.CONTROL, "Y"));
    driver.findElement(By.name("3")).submit();
    driver.findElement(By.name("3")).sendKeys(Keys.valueOf("Y"));

I Just want to press one letter or multiple letters from my keyboard.

Thanks.
