Start level blueprint when playing sequence?

Hi, I’ve setup a level blueprint which activates when I press Play Game or run simulation. It causes a timeline to control the movement of a material. However this doesn’t trigger when I play the shots I’ve setup in sequencer (I’m making a cinematic).

This is the level blueprint

Can anyone tell me what I need to do for this to activate in Sequencer please? I’ve got the same issue in getting a morph target to play (works in game or simulation but not sequencer) and I think that it’s probably the same solution for both.
