Go to the Game Launcher app and update to the most recent version of the Samsung OS to link your account. The app's icon appears as follows:
The "Sign in/sign up" page for the Discord Samsung integration should now appear when you click on the Discord logo in the top right corner of the app.
The account linking process will start as soon as you click "Sign In" if you already have a Discord account.
You might see the screen below. In such case, be sure to select "Open with Discord"
Once the connecting is complete, your Activity Feed will now appear. Here, you can view the games that your friends have recently played as well as the voice channels or games they are now participating in.
