I received FB email saying

Your app is currently accessing Graph API v13.0 which will reach the end of its 2-year lifetime on 28 May, 2024. We estimate 7 endpoints that App calls will be impacted by this change and may stop working after the automatic upgrade push.

However, when I go to the API Upgrade Tool, it said

Your app has no changes for the methods you selected between v13.0 and v19.0

Does it mean I don’t need to do anything, e.g. upgrade my FB client library?
