I can see that there are many questions raised for this but those are very old and I think that will not work with current Jira API because I tried each article but nothing worked.
Can anyone please help me? I want to add an icon to the web item. Below are the web-item content or module that I have added in atlassian-plugin.xml.
<web-item name="test-web-item" key="test-web-item" section="jira.issue.tools" weight="0">
<description key="Testing">This is for testing</description>
<icon height="16" width="16">
