You click a button but nothing happens in Selenium. How do you debug it?

// Try switching to iframe first
driver.switchTo().frame("frameName");
driver.findElement(By.id("myButton")).click();
driver.switchTo().defaultContent(); // switch back

WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(10));
WebElement btn = wait.until(
    ExpectedConditions.elementToBeClickable(By.id("submitBtn"))
);
btn.click();

// Scroll element into view first
JavascriptExecutor js = (JavascriptExecutor) driver;
js.executeScript("arguments[0].scrollIntoView({block:'center'});", btn);
btn.click();

// Bypasses overlays, CSS pointer-events:none, and visibility issues
JavascriptExecutor js = (JavascriptExecutor) driver;
js.executeScript("arguments[0].click();", btn);

// Simulates real mouse movement + click
Actions actions = new Actions(driver);
actions.moveToElement(btn).click().perform();

// Read browser console logs
LogEntries logs = driver.manage().logs().get(LogType.BROWSER);
for (LogEntry entry : logs) {
    System.out.println(entry.getMessage());
}
