GrideApp error in GalleryImageAdapter

[maurotello]

Hello! In principle, thank you for sharing your knowledge.
I'm following the tutorial but it throws me an error in GlideApp, it doesn't recognize it and nowhere in the code is that class

GlideApp.with(context!!) .load(image.imageUrl) .centerCrop() .diskCacheStrategy(DiskCacheStrategy.ALL) .into(itemView.ivGalleryImage)

in

class GalleryImageAdapter(private val itemList: List<Image>) : RecyclerView.Adapter<GalleryImageAdapter.ViewHolder>() {

Thanks
