                    sizeTextModifications = {
                        textAlignment = TextView.TEXT_ALIGNMENT_VIEW_START
                        textStyle = SizeTextModifier.TextStyle.NORMAL
                        margin = 22 // use dp or sp this is only for demonstration purposes
                        textColor = Color.BLACK
                        textPadding = 5 // use dp or sp this is only for demonstration purposes
                        textSize = 12f  // use sp this is only for demonstration purposes
                        backgroundDrawable = R.drawable.rounded_bg_abstract_dialog
                    }
            )
        }, ::doSomethingWithVideoList)
    

If you're using Fragments to call the pickers you can leverage set fragment result listener to get back the result and you don't have to restore the listener nor provide a lambda for the listener, it can be as simple as

SingleVideoPicker.showPicker(requireContext())

setFragmentResultListener(SingleVideoPicker.SINGLE_VIDEO_REQUEST_KEY) { _, bundle ->
    val loadedModel = bundle.getParcelable<VideoModel>(SingleVideoPicker.ON_SINGLE_VIDEO_PICK_KEY)
            loadedModel?.let { loadVideo(it) }
        }
        
setFragmentResultListener(MultiVideoPicker.MULTI_VIDEO_REQUEST_KEY) { _, bundle ->
    val loadedModel = bundle.getParcelableArrayList<VideoModel>(MultiVideoPicker.ON_MULTI_VIDEO_PICK_KEY)
            loadedModel?.let { doSomethingWithVideoList(it) }
        }
