Niegara Particles not visible under water (water experimental plugin) / Water Simulation

First, I apologize, I am quite new and trying to figure out even how simple things work out.

  • Issue #01
    • So I have the water that I made using the plugin water, and then I have some stones
      and stuff beneath all working fine I mean they are visible (can be seen inside the
      water), then I want to add some bubble-like particles made with Niagara and they are
      not visible, they are visible but only after coming out of the water.
  1. Any idea about it?
  2. Do I need to make the water in Niagara as well or is there another simpler solution for it?
  • Issue #02
    • My main goal was, to have a small pool of water, and I needed bubbles coming out
      from the bottom of the water and then making the water like it was boiling or
      something. But, forget the bubbles if I can only make the area of the water start
      bubbling, that would be great. I need this to happen only to a specific radius, not the
      whole thing.

Any suggestions would be awesome, I tried to look around on YouTube about it, but little did I find. Just anything would help me a lot. Thanks :::
