When will HTTP/2 support be available for methods like sendEach() and sendEachForMulticast() in the Firebase Admin Java SDK?

It appears that this support has already been implemented in firebase-admin-node.
https://github.com/firebase/firebase-admin-node/releases/tag/v12.3.0

I was informed that after implementing HTTP/2 in firebase-admin-node, the same would be applied to firebase-admin-java.
