How to get lifecycle.coroutineScope with new androidx.lifecycle:*:2.2.0-alpha01

Question

On 7th May, 2019 androidx.lifecycle:*:2.2.0-alpha01 was released announcing:

This release adds new features that adds support for Kotlin coroutines for Lifecycle and LiveData. Detailed documentation on them can be found here.

On documentation it's mentioned that I can get the LifecycleScope:

either via lifecycle.coroutineScope or lifecycleOwner.lifecycleScope properties

But it seems that I'm not able to find none of them. My current dependencises are:

def lifecycle_ver = "2.2.0-alpha01"
implementation "androidx.lifecycle:lifecycle-extensions:$lifecycle_ver"
implementation "androidx.lifecycle:lifecycle-viewmodel-ktx:$lifecycle_ver"
implementation "androidx.lifecycle:lifecycle-common-java8:$lifecycle_ver"

implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-core:1.2.1'
implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-android:1.2.1'

What may be the cause and how do get these apis?

I actually spent a couple hours trying to figure this out myself and it turns out it is in a new package that only exists as of the alpha. Add this and you should be good to go.

implementation "androidx.lifecycle:lifecycle-runtime-ktx:$lifecycle_ver"
