Simple cartoon Water with effects

Hello everyone and thank you for taking the time to look at my post.

I am a young French developer and I would like to create a small independent game to train and take pleasure in realizing it.

Since 1 week now, I try to create and work with water and especially its rendering.

I have done many tests with several possible combinations like using the shader graph and I have probably seen all the youtube videos about it ahah

Compared to this superb video .. Do you have an idea of the methods or processes used to have these small particles around the obstacles, this transparency that also wants to be more opaque and that emits a reflection etc .. (Nb: This video is tour on Unity)

If you have advice I'm really interested and I thank you in advance, it's a big challenge for me to get a similar rendering with water on my little game.
