Access token: readAs and ActAs: ledger link with sub?

In this example:

07:36:51.113 [daml.index.db.threadpool.connection.api-server-0] INFO c.d.p.u.PersistentUserManagementStore - Granted 1 user rights to user 79c64b59-0a4e-4565-acac-37f5377d7257-alice-user: CanActAs(b8f75500-b76a-44aa-a996-8f474d1ec48e) , context: {participantId: “sandbox-participant”, submissionId: “3d431421-7858-4330-a481-fae1d65f25ec”}

how does submissionId tie into the ledger transaction? Is there an actual lineage between the log and the transaction?

(or maybe this is a poor example. Will have to test further to extract the log(s) and see where a linkage can be made).
