Visualize Specific Position of a Kibana List Field

Question

I have a kibana list application.details.features.feature_vector with ex:

1. [10,50,30,100,99]
2. [21,60,59,199,99]
3. [41,50,21,55,0]

If I want to extract the 2nd position from this vector to get min/max/mean stats on it how would I proceed?

Trying to do something like application.details.features.feature_vector[1] like I would do on a python list but doesn't seem to accept this.
