Extract all specified waypoints and draggable routes from Google Maps link [closed]

In the URL below, there are 4 waypoints and 1 draggable waypoint (Moss Vale) which changes the default routing.

Example URL:https://www.google.com.au/maps/dir/Sydney+NSW/Blacktown+NSW/Gosford+NSW/Berry+NSW/@-34.028932,150.7037699,9.21z/data=!4m31!4m30!1m5!1m1!1s0x6b129838f39a743f:0x3017d681632a850!2m2!1d151.2092955!2d-33.8688197!1m5!1m1!1s0x6b12976ef7ab2f15:0x5017d681632aa80!2m2!1d150.9126927!2d-33.7660982!1m10!1m1!1s0x6b72cc66d49a0d71:0x5017d681632d9a0!2m2!1d151.341667!2d-33.426667!3m4!1m2!1d150.3800621!2d-34.5456527!3s0x6b1397690ec9ec61:0x7b462dca1181014a!1m5!1m1!1s0x6b137bedae28f8ef:0x5017d681632e130!2m2!1d150.6988896!2d-34.7757734!3e0?entry=ttu

I want my Python script to be able to extract:

1. All the waypoints i.e. Sydney, Blacktown, Gosford, Berry (circled in black)
2. All draggable waypoints i.e. Moss Vale (circled in red)from the url.

Annotated Google Maps Image for reference

For reference, how do i decode/encode the url parameters for the new google maps?

This old post tackles the similar issue but finding it hard to implement a scalable solution.
