The issue is that Google anunce the new version to connect with their Push notification service as you can see here:
https://firebase.google.com/docs/cloud-messaging/migrate-v1?authuser=6
Apps using the deprecated FCM legacy APIs for HTTP and XMPP should migrate to the HTTP v1 API at the earliest opportunity. Sending messages (including upstream messages) with those APIs was deprecated on June 20, 2023, and will be removed on June 21, 2024.
We cannot set the Google Cloud Messaging API Key as your module ask on this path:
/admin/config/services/push_notifications/configuration
Change the code to use the new method proposed by Google.
