Hello @Pedr0g0mes, Welcome to the community forum and thanks for posting.
The option should show under the 'Payments' tab. If it is still not showing in your account, please try clearing your cache and cookies or try using a different internet browser to access your account. If you are attempting to log in through the mobile app, please try uninstalling and reinstalling the app to see if this helps to resolve the issue.
