To delete a Pokémon Go account that is linked to your Facebook account, you will need to follow these steps:
1. Open the Facebook app on your mobile device or go to the Facebook website on your computer.
2. Tap on the menu icon (three horizontal lines) located in the top right corner of the app or website.
3. Scroll down and tap on “Settings”.
4. In the Settings menu, tap on “Apps and Websites”. This will show you a list of all the apps and websites that you have logged in with your Facebook account.
5. Look for the Pokémon Go app in the list and tap on it. If you can’t find it, you can use the search bar at the top to search for it specifically.
6. Once you have selected the Pokémon Go app, you will be taken to its settings page. Here, you will have various options related to the app.
7. Scroll down to the bottom of the page and tap on the “Remove” button. This will prompt a confirmation message.
8. Read the confirmation message and tap on “Remove” again to confirm the deletion of the Pokémon Go app.
9. After confirming, Facebook will remove the app and all its associated data from your account.
Please note that deleting the Pokémon Go app from your Facebook account will not delete your actual Pokémon Go account. If you want to completely delete your Pokémon Go account, you will need to go through the game’s own account deletion process, which may vary depending on the platform you are using (iOS or Android).
