Unreal quest 3 standalone web multiplayer

Trying to connect 2 peoples in one environment via internet. No luck.

I can use EOS, but quest overlaying it's own services, which hardly communicate with EOS.

In oculus samples there is a Unreal-Discover sample, but after recompiling it and uploading it on Meta store, it won't start. 

The main thing that this sample is overloaded, and hard to understand, where is error located. 

Any link or tutorial about quest web multiplayer?
