Firebase Cloud Messaging: "undefined" database getting created in IndexedDB

Question

I am implementing web push notification with Firebase Cloud Messaging (FCM). I have followed the documentation for setup a javascript firebase cloud messaging and completed initial implementation for my app. I am able to receive messages from firebase. But, I noticed that a database has created in IndexedDB and it named as undefined. This database contains a single store called fcm_token_object_Store, which all auth, endpoint, fcmSenderId, fcmToken, etc.

Please refer the following screenshot:

Question: Can this database_name is configurable? So that we can query in the application.
