SEQUENCER - PLAYING with GAMEPLAY

Not sure if this has been covered or not, but when we’re creating our Sequencer Shots, everything works on the camera side how we want, but the environment and all dynamic assets including characters and meshes are all frozen ie. just not active Im assuming, is there a way to start the game / environment map when your Sequencer start your cinematic? If so, how please.

Does Sequencer have any options to allow you to fire off what you want
to move in the scene? Or does it just move only the camera?
