You could start by checking the menu options of the platform. There might be a 'Muted' or 'Hidden' section. Another option is to search using relevant keywords related to the muted stories you're looking for.
It could mean stories that haven't been given much attention or publicity, sort of like they've been 'muted' or silenced. Or maybe they have a more understated tone or mood.
Muted accounts generally cannot interact with your story. Since muting is a way to cut off or limit an account's access to your content, it naturally extends to your story. Interaction with a story could involve viewing, reacting, or commenting. But when an account is muted, they are prevented from doing any of these things in relation to your story. It's a way to control who can engage with your personal content.
