儘量等到目標按鈕變爲可見：

WebDriverWait wait = new WebDriverWait(driver, 10); 
wait.until(ExpectedConditions.invisibilityOfElementLocated(By.xpath("//div[@id='firsttimeloading']"))); 
WebElement button = wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//button[@tooltip='Add Asset']"))); 
button.click();
