I am trying to make a link to a forum post, but I want it to go to the Destiny 2 app and not the Bungie .net website. Here is what I have.
Edit: weird, so from here it links to the app, but on discord it links to the website.
That's because of the settings in the users Discord app account.
Discord opens up a browser window within Discord unless you go to your User Settings > Behavior > Chat Behavior > Use Chrome Custom Tabs, if you turn that off you will then get the option to open Bungie.net links in the Destiny App.
