Removing Hiss

Attempting to remove hiss from audio track off a video.

I'm aware that one (and maybe the best) technique is to 'learn' hiss on a section of audio which ONLY has hiss and no other sound using an audio editor. This 'learning' creates a mask which is then applied to other parts of the audio which contains hiss and other sounds (voice, music, effects). The mask then effectively removes the hiss leaving only the wanted sounds such as voice, music and effects.

However, in my case here, there is no section of audio which contains the hiss ONLY to 'learn' as a mask. So using the mask technique is not really an option here.

So, how to remove hiss only from audio that also has other (wanted) sounds?

Sample audio enclosed. The clip has music and some effects as well as the hiss. Want to remove the hiss only from the sample clip.

The music is buried pretty deep in the noise.

Deconstruct in Izotope RX divides the signal into "tonal" and "noise", used it here to reduce the noise,
no noise print necessary

Thank you very much!

The result is pretty good!

Any particular settings in Deconstruct, or just use the default settings?

Approx. Tonal/Noisy balance -1.7 and Noisy Gain [db] -12
