Hi, I have a hard time wrapping my head about `Coroutines` with `Promises`.
Promises are an async callback construct, so in my mind it would make sense to use them with `Coroutines`
For simplicity, let's say we have this function from a 3rd party lib:
```fun fetchUser(): Promise<User>```
How would it look to launch a `Coroutine` that calls this function and returns the `Promise`?
```fun mustReturnPromise: Promise<User> {
  // ?
  CoroutineScope(CoroutineName("")).launch {
    // ?
	fetchUser()
  }
  return // ?
}```
For a more concise case I tried to follow <https://stackoverflow.com/questions/76160628/axios-interceptor-on-request-does-not-wait-for-await-function-calls-to-be-finish|this> when implementing `Aaxios` interceptors, but I am somewhat stuck at
```const newTokens = await refreshTokenPromise;```
since there is no `runBlocking` in KotlinJS and to `.await()` it has to be a suspend function.
