How to take mileage from Google maps from point to point, for use in calculations on the site?

Question

Google Maps

Actually, the task is to embed Google maps on the site, on which you can set the route, and you need the length of this route, and of course, transfer the departure points to variables to be used in calculations on JS and in forms. Maybe someone knows guides, or links to documentation, or maybe someone has already done this?
