video – How to make animation of floating particles on Photoshop portable?

I want to make a gif of Ash particles floating in the air on Photoshop portable, I know how to make the particles follow a specific trajectory but that’s not exactly what I want, I want the particles to “randomly” move in the air so it can look more realistic.

Is this possible in Photoshop portable?

If yes, can you explain how to do it?
