How to get directions on Google Maps without leaving the site?

Question

Google Maps

In general, there is the following situation:
On the company's website, in the footer, there is a standard block "How to find us" and it also contains a Google map in an iframe. The point (marker) of the company's location is marked on the map with coordinates.
The task is as follows : the point indicated on the map is actually point B (the end of the route), i.e. when the user clicks on this marker, an input line and a "Paste" button should appear. When the user has entered the address from which he will have to get (point A) and clicked the "Paste" button, it is necessary for google to plot a route to point B (with fixed coordinates) without leaving the site page with its standard means. by default, google opens its large map when getting directions.
Is it possible to do this and what would you advise to "read" about it?
