Protractor 无法使用量角器单击平铺

我是量角器的新用户。需要帮助，因为我无法点击一些名字，下面有HTML

<div class="department-click" 
<div class="department-click" onclick="GLOBAL_SERVICE_ID=405;changeLocation('#/aaaa');_routeFrom='home'">
   <!-- <div class="department-click" onclick="changeLocation('#/aaaa')"> -->
   <div class="department-icon custom-svgbg1 layout-column layout-align-center-center">
      <!--                  <svg style="height:80px; width:80px;" viewBox="0 0 24 24"> -->

尝试通过css定位元素：

element(by.css('.department-click .clamp2 span'));

根据要单击的元素，下一行是通过css定位元素，然后单击它：

element(by.css('h3.clamp2 span')).click();

请展示你已经做过的尝试。这将是一个更好的答案，并提供一些解释
