How to quickly make a map with routes to insert on the site?

Question

Google Maps

You need such a feature:
You draw a route (for example, on Google / Yandex maps) and then insert this route on your website so that this case can also be opened via mobile phones.
I poked around in both Google maps and Yandex, I just can’t find what I need, in one you need to find out the latitude and longitude, in the other they draw everything on one map and porridge forms there.
I need simplicity, I drew a path on the map (from point A to point B with intermediate points (that is, drive from this street to this and from this to this)), I took this data and inserted it on my website, then for another route the same way drew took and pasted on the site.
I will be very grateful

Answer 1

You can draw a route in Yandex and copy the url

Answer 2

It seems to me that this is a task for leaflet.js
And you can take OpenStreetMap as a substrate.
