How do I add a subtask to an issue in Jira?

If you are a project manager or team member working on a project in Jira, you may need to add a subtask to an existing issue in order to break down a larger task into smaller, more manageable pieces. This can help you better track progress and ensure that all aspects of the task are completed. Additionally, adding subtasks can help you assign specific tasks to different team members, allowing for better collaboration and accountability.
