Cant find insert particle effects

I cant find any tool to insert particle effect in Harmony stage advanced -trial. Where can i find that?

you can’t do that.
because the advanced version has not node view(Network view).

I have also the stand alone - trial,so i need the upgrade to stage 12 premium (standalone)?

Yes, now that they are eliminating Animate Pro by not having a level of Harmony 12 specifically coinciding with it the only option for node base effects is Harmony 12 Premium.
