Shuffle array of array pyspark columns

I have pyspark column Like this:

                   gm_array
[[1, 4, 6,...], [2, 7, 8,...], [3, 5, 7,...],...]
[[8, 11, 9,...], [7, 2, 6,...], [10, 9, 8,...],...]
[[90, 13, 67,...], [55, 6, 98,...], [1, 6, 2,...],...]
.
.

Now I want to shuffle this single array and also array inside this array, and then I want to pick 5 first element from first 5 array.

                  gm_array
