How to check if an array is superset of another

[kartik-579]

I have an usecase where i want to check that my input array has all the elements of a given array (superset checking). I checked the docs but am still unable to find the solution to this. Can someone please help me with this?

One possibility is you could check that all of your subset is in the superset using a predicate expression, like
"all([1,2,3], {# in [1,2,3,4,5]})"
