Kotlinx.serialization: cbor package not found in Android Kotlin

[lonevetad]

Describe the bug
I try to import the package _cbor_ from kotlinx.serialization.cbor* but it says _Unresolved reference: cbor_
Also, the class Cbor isn't available (even if _Json_ class is available and working)

I've tried in many ways, also copy-and-pasting the original code of the CBor class, but an error upon deserialization occurred (something like "started to find a map but found 79, I don't remember right now, but this problem has a lower priority because it's caused by brutally copied code).

My build.gradle (Project: nameOfThatProject) looks like:

buildscript {
ext.kotlin_version = '1.3.72' // '1.3.70' //
ext.serialization_version = '1.3.72'
ext.serialization_plugin_version = '1.3.72'

To Reproduce
Just copy the build.gradle fileS and try to use the Cbor class to decode an object from a string.

Expected behavior
Importing cbor subpackage and founding the Cbor class

Environment

• Kotlin version: 1.3.72
• Library version: [e.g. 0.11.0] ???
• Kotlin platforms: JVM, probably also Native
• Gradle version: 3.6 [i guess]
• IDE version (if bug is related to the IDE) [e.g. IntellijIDEA 2019.1, Android Studio 3.4]
• Other relevant context [e.g. OS version, JRE version, ... ]

Cbor is an artifact of its own. Look here:

Thank you for your link. So, how I add that artifact to the project? I'm sorry if I appear a bit noob in this context.

Add

implementation "org.jetbrains.kotlinx:kotlinx-serialization-runtime:0.20.0"
implementation "org.jetbrains.kotlinx:kotlinx-serialization-cbor:0.20.0" 

to your dependencies {} section

Also, 'org.jetbrains.kotlinx:kotlinx-gradle-serialization-plugin:0.7.0-eap-1' is indeed obsolete and should not be used.
