Coroutines, how to call async, await, launch functions?

Question

Kotlin

I connected the libraries
implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-android:1.3.9'
implementation "org.jetbrains.kotlinx:kotlinx-coroutines-core:1.3.8"
I can only use CoroutineScope(), but the lessons say about async, await, launch... without any additions

Answer 1

async and launch can only be called on a scope, and await is a suspend function, it can only be called from other suspend functions.
