Check the Browser compatibility table carefully before using this in production.

The MediaKeySession.closed read-only property returns a Promise signaling when a MediaKeySession closes. This promise can only be fulfilled and is never rejected. Closing a session means that licenses and keys associated with it are no longer valid for decrypting media data.
