Contains Function - microsoft/MIMWAL GitHub Wiki
bool Contains(values:List<object>, value:object)
Returns a Boolean value indicating whether the value exists in the list of values. Comparisons for strings are performed without case sensitivity.
If any input parameter is null, the function returns false. The first input parameter can be a list of objects or a single object.
If the first input parameter is a single object, then the function tests for equality (and for strings without case-sensitivity).
If you are intending to determine if a string value contains a substring value, you should use the RegexMatch function instead.
