How to check coordinates by polygon Yandex maps?

Question

Yandex maps

Hello, I drew 4 delivery zones for Moscow. Exported to JSON and imported to my project (The project on React is therefore easily imported). I have the coordinates of the address I need.
And there is also a features constant, which has 4 elements (4 zones) and each zone has coordinates (which forms the polygon). How to check if the address is included in the given polygon. Thanks in advance

Answer 1

Yandex has a whole ready-made example for this case, is it really so difficult to use the search?

I’m silent that even here it was sucked dozens of times.
