Question regarding how road closures are handled in MRA NN version 5.2

[BMWBiker58]

The rerouting options introduced in version 5.2 for dealing with sudden road closures are, for me personally, an extremely important feature.
However, I am not yet sure which of the three options I should choose and what the associated behaviour is.

My most common scenario is:
I am following a route on the motorway. Suddenly, I come across a closure on a motorway exit that I was supposed to take to join the next motorway. No immediate shaping or via points have been set for this section.

Which of the three options should I choose?

Preferred outcome:
I simply want to be guided back onto the route. Any shaping points or waypoints set further along the route in the near can be ignored. The main thing is that I am guided back onto the route without having to rely on my – non-existent – sense of direction and without being rerouted, as has happened in the past.

Please bear in mind that this scenario takes place on a motorway and you are not allowed to stop to adjust any settings.

A clarification of the three alternatives and a step-by-step description of the necessary button presses would be greatly appreciated.

Additionally, I would like to ask whether selecting one of the three methods and button sequences also works with an Apple CarPlay device.

Thank you very much for your support!
