Change Posts Icon

How can you change posts icon in WordPress? This use case shows how a focused WordPress code snippet can handle the task without installing a heavy plugin. The snippet should change the Posts menu icon to a newspaper icon and produce this result: The renamed News menu uses a newspaper-style Dashicon. You can also log in to LeonLab.ai, describe this WordPress use case in plain English, generate the snippet, review the PHP code, and deploy it to the selected WordPress project.
