      .into(object : CustomTarget<Bitmap>() {
           override fun onLoadCleared(placeholder: Drawable?) {}

           override fun onResourceReady(bitmap: Bitmap, transition: Transition<in Bitmap>?) {
               val roundedBitmapDrawable = RoundedBitmapDrawableFactory.create(resources, bitmap)
               roundedBitmapDrawable.isCircular = true
               icon.setImageDrawable(roundedBitmapDrawable)
            }
