Denoiser issue

[vfxfreek]

Hello guys,
I'm currently having a weird issue, I'm not sure if it's a bug or I'm doing something wrong or we still can't use it, but the Denoiser doesn't work in Picture Viewer (Render Viewer)
It works perfectly in the Live Viewer but not in the Picture Viewer.
Any ideas what might be the cause of that issue ?

Did you enabled the related render pass?

Oh I haven't thought of that, so I have to render it with Denoiser Passes and then apply them in AE just like the usual passes ?
So stupid from my side, how haven't I thought of it...
