Multiple row of chips in chipgroup

Question

I'm fetching a list from my API of for example 25 tags of country such as, Germany, England, France, Italy etc... I'd like to have 2 row with 10 chips per row, and if I get 30 tags the next time I fetch I want to have 3 row of 10 chips etc...

So far I haven't found anything allowing me to do that. I've taken a quick look at Flexbox-Layout but it doesn't seem to fit my needs, I currently have the code below, but I was thinking of doing such logic with a Recyclerview

Fragment

viewModel.videoSelected.observe(viewLifecycleOwner, object : Observer<VideoPage> {
            override fun onChanged(videoPage: VideoPage?) {
                videoPage?.tags ?: return
                val chipGroup = binding.chipGroup
                val chipGroupInflater = LayoutInflater.from(chipGroup.context)
                val children = videoPage.tags.map { tagName ->
                    val chip = chipGroupInflater.inflate(R.layout.chip_video_tag, chipGroup, false) as Chip
                    chip.text = tagName
                    chip.tag = tagName
                    chip.setOnClickListener {
                        Toast.makeText(context, tagName, Toast.LENGTH_SHORT).show()
                    }

                    chip
                }

                for (chip in children) {
                    chipGroup.addView(chip)
                }
            }
        })

and the result is the 25 chips in one line. How can I make it so that it's divide on multiple line ?

I've also manage to do it in a more simple way with BindingAdapter:

 <androidx.recyclerview.widget.RecyclerView
                    app:listVideoTagChip="@{viewModel.videoSelected.tags}"
                    android:id="@+id/rv_video_chips"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    app:layoutManager="androidx.recyclerview.widget.StaggeredGridLayoutManager"
                    android:orientation="horizontal"
                    tools:listitem="@layout/chip_video_tag"/>

private const val TAG_PER_ROW = 10

@BindingAdapter("listVideoTagChip")
fun RecyclerView.bindRecyclerView(data: List<String>?) {
    val adapter: VideoTagAdapter = this.adapter as VideoTagAdapter
    (layoutManager as StaggeredGridLayoutManager).spanCount =
        data?.size?.let {
            ceil(it.toDouble().div(TAG_PER_ROW)).toInt()
        } ?: 1
    adapter.submitList(data)
}
