Is it possible to open external app from stories or posts in instagram? (or instagram webview if not possible)?

In my app users can create content and share it on instagram, Facebook and other channels. We want users on instagram that reach that content through posts or stories to be able to open the shared content on our app. If this is not possible directly (from the feed or the story) we would like to do it by loading our website on the instagram webview and from there make the user press on "Open/Download in XXXXX app", for example.

Which is the best approach of this feature? is it possible?

Thank you!
