I would like to zip two upload progress listener into one. Any advice?

val avatarProgressChannel = Channel<Int>()
val thumbnailProgressChannel = Channel<Int>()

avatarTask.addOnProgressListener { progress ->
  avatarProgressChannel.offer(progress) // 0, 1, 2, ..., 100
}

thumbnailTask.addOnProgressListener { progress ->
  thumbnailProgressChannel.offer(progress) // 0, 1, 2, ..., 100
}

avatarProgressChannel.zip(thumbnailProgressChannel) { p1, p2 -> p1 + p2 }
  .consumeAsFlow()
  .asLiveData() // expose to UI layer, emit 0, 1, 2, ..., 200
