Check if a string exists in an Immutable.Set<string[]>

Question

Here is a mock of what I have tried with each outcome... I've read over the documentation and it seems like at least some of these things should work. Not sure what I'm doing wrong.

function getMatch(
  value: string
  fooSet: Immutable.Set<string[]>
): boolean {
  // Convert the Immutable Set to a regular JavaScript array so i can use includes
  const setArray = fooSet.toArray(); 
  return setArray.includes([value]); //TypeError: fooSet.toArray is not a function
  // Use the some method to check if value exists in set
  let valueList = [value]
  return fooSet.some((key) => key === valueList); // fooSet.some is not a function
  return fooSet.has([value]);  //has is only for numbers can't be used on strings
  return fooSet.some((key) => key.is(value))//Property 'is' does not exist on type 'string[]'
  let found = fooSet.get([value]) 
  return found ? true : false //fooSet.get is not a function
}

UPDATE SOLUTION: changed to Set<List> which was a great improvement @Bergi. The other half was i needed to compare immutable to immutable, my value was a 3 string key so this was the fix:

function getMatch(
  values: { key1: string: key2: string; key3: string }
  fooSet: Immutable.Set<List<string>>
): boolean {
  const { key1, key2, key3 } = values
  const valueList = Immutable.List<string>([key1, key2, key3])
  return containsValue = fooSet.some((list) => list.equals(valueList));
}

I can also just look for one value in the list...

const checkKey1 = (list: Immutable.List<string>) => list.includes(key1);
const hasKey1 = set.some(checkKey1);
