How can I open the emitters of the praticle systems in folder 'startercontent'?

Hey all!
I’m using the fire praticle system in folder ‘startercontent’ to light up my scene,but the fire disappeared when I move the screen out of it,so I want to open the emmiter of the praticle system,and turned off ‘fixed bounds’ to solve the problem.
But I just can’t find the way to open the emmiters of the praticle system.
Thank you, for any help!

Sorry,I didn’t put out the picture of the emitter I want to open,I have added the picture,could you take a look,thanks :smiling_face_with_three_hearts:

is Niagara.

You can’t use the Cascade interface on a Niagara particle system. Cascade is being phased out.
