Need English descriptions of what the code is intended to do

[abhardwaj-dev]

Issue in ./help/using/building-journeys/expression/collection-management-functions.md

Under the section "Other examples" all it shows is two pieces of code without any explanation of what the expression is supposed to return. Could we please include a short description like "This expression returns the second push notification token of the list." found in the example above this section?

Thanks for raising this @abhardwaj-dev we'll update this section Internal reference > DOCAC-11077
