It's like a massive stadium chant in the background (far distance breathy/airy tone), great reverb in the mid distance and clear in the close distance.

I tried to reproduce all of those effects and I got a "closer result" using crowd chamber plugin and the far mic position of a kontakt choir library and doing some automations with its 2 mic positions, also I added a good reverb. However I want your suggestions for a better way to get what I said above.

Please try to hear all the choir part because the effect is more accentuated in some intervals.
