How to put beeline tiles on a Yandex map?

Question

JavaScript

Hello.
There was a need to impose beeline coverage maps on Yandex maps. The layer address is formed as h01tiles2.tmcrussia.com/bee2g-sem/lv10/00/000/000/...
Accordingly, I cannot find a relationship between what coordinates are transmitted to Yandex and how the address is formed. I came across this https://jsfiddle.net/c8133nwt/16/ but it's also not entirely clear what coordinates are transmitted there as x and y. Perhaps someone has come across something similar?
I tried to figure out the JS that generates the map, but I can't antex-shop.ru/catalog/view/javascript/gsm/beeline/...

Bayan is not mine, but they say the earth is not round

As far as I know, I may be wrong:
- Google Maps uses EPSG=3785 Mercator projection from a spheroid (a=6378137,b=6378137)
- Yandex maps uses EPSG=3395 Mercator projection from an ellipsoid (a=6378137,b=6356752)

Beeline tiles are most likely in the Google, spheroid projection.
