FMOD Unity WebGL

I am using FMOD to implement audio in Unity.
I’ve added various sounds to some objects in the game.
Now I want to build a game and see if it works.
I need to use WebGL format.
I switched platforms, but then Unity gave me an error saying “FMOD Studio: copy banks for platform WebGL : Unsupported platform”
I am new to all of this.
I downloaded FMOD 2.0, it said that it can support web formats…
So what’s wrong?
Is it possible to make a game using FMOD?
Do you need to use entirely different scripts?
Is there some manual where you can read all of this, because tutorials on YouTube are either quite difficult or just not about what I’m looking for.

FMOD for Unity does support WebGL, what versions of FMOD and Unity are you using?
