Query a navigation session
When you have obtained a navigation id through the startNavigation mutation, you can query for its current state.
Query
To query the navigation details you will need to provide the navigation ID as an argument. For doing turn-by-turn navigation we strongly recommend you to use the subscription service. A subscription provides you with updates on the navigation session whilst a navigation query only gives you a snapshot of the current state.
