How to use BestOf2NearestMatcher apply2()?

This is probably a simple answer but I am new to javacv. I am translating some python to javacv and I am having issues calling the apply2 function of the BestOf2NearestMatcher. I am trying to pass a list of ImageFeatures as the first parameter but I am getting a type mismatch error. The documentation for apply2 says it accepts StdVector opencv_stitching.ImageFeatures. How can I convert my List to properly pass to the apply2 function?

Here is my function

fun matchFeatures(features: List<ImageFeatures>) : MatchesInfo {
    var matcher = BestOf2NearestMatcher.create()
    var pairwise_matches = MatchesInfo()
    matcher.apply2(features, pairwise_matches)
    return pairwise_matches
}
