You can use:
yourelement.sendKeys(Keys.RETURN)
or .sendKeys(Keys.ENTER)
: which is an equivalent of focusing that element and hitting RETURN/ENTER on that element
Also, There are methods to do this using Javacript but it is not usually recommended:
using the non-native Javascript Executor:
((JavascriptExecutor) driver).executeScript("arguments[0].click();", yourelement);
or by using Javascript Library:
JavascriptLibrary jsLib = new JavascriptLibrary();`
jsLib.callEmbeddedSelenium(driver, "triggerMouseEventAt", we, "click", "0,0");
