How to get objects with a object tag name in Sequencer using C++

I would like to know the code to get objects with a object tag name in a Sequencer track.

Normally, in a game environment, when you run the Sequencer using CreateLevelSequencePlayer function, an ALevelSequenceActor is created, allowing you to find objects with the tag name. However, in the Sequencer editing mode in PIE mode, there is no ALevelSequenceActor. Does anyone know how to find objects with a tag name in a Sequencer track without an ALevelSequenceActor?
