Hello! You need to implement such a map, there is an office, and you need to build 2 routes to it, one from the metro (on foot) the second from the road (by car), you need to draw a broken line manually, there is an example where it works correctly as it should, only done through the old api and still with a bunch of code mixed with the Bitrix code, I'm suffering for 2 hours, nothing happens, please tell me how to do it? Here is an example polinov.ru/contacts
