How to mute sound just on Instagram stories?

I have an Android smartphone. I wish to mute sound on Instagram stories, which can be achieved easily by using the volume buttons. However, in that case I need to unmute sound when I want to watch a video on YouTube or listen to a voice message on WhatsApp etc. and it's very annoying. I want my sound to remain unmuted, but to automatically mute when I open Instagram stories without me having to do this manually. How can this be achieved? Edit: I'm obviously thinking about other people's stories, I wish to mute sound while watching other people's stories. It's fairly easy to mute sound when I am uploading my own story and this question is not about that.
