You might need to look for the settings or options within the platform where the private story is hosted. Usually, there's a specific option to manage your participation or remove yourself.
Well, it depends on the platform. For example, on some social media apps, you'd go to the story settings and look for something like 'leave' or 'remove from story'. But make sure you follow the platform's guidelines to do it properly.
To remove yourself from a private story, first check if there's an icon or menu related to the story. Sometimes it could be a three-dot menu or a gear icon. Click on that and look for the option to remove or exit the story. It can vary depending on the specific app or website though.
