What is the way to do a permalink that asks the person to download the app if they don’t have it? Otherwise, it should open the specific post.
My app has ‘posts’ which can be shared with a permalink to the specific post on various platforms. The thing is, for this to happen I assume there should be a web presence. But once you go to the specific link it should open in the app. If the person viewing doesn’t have the app it should prompt him to download.
