How do I replace the windscreen wiper blades on my 2019 Jaguar XF?  (This is the X260 model)

I cannot seem to get the blades to the service position as shown in the owners handbook?

Also I am unsure as to how the blades  actually clip on or are taken off. 

Ca anyone help please?

All sorted, read the handbook and assume the wiper up position is the same as the wiper down described in the handbook. Then press the square button and push off
