How to make an asynchronous API call from token provider?

[monil-shah-13]

We are using the token provider from the SDK which has a method loadToken that returns a string. From there we make an API call to our backend to generate a token. As the function needs to return a string, we need to make the API call using runBlocking using following code:

val streamTokenProvider = object : TokenProvider {
            override fun loadToken(): String = getChatToken()
        }

fun getChatToken(): String {
        var chatToken = ""
        runBlocking {
            when (val result = repository.getChatToken()) {
                is ResponseResource.Success -> {
                    result.value.chatTokenDetails.token?.let { token ->
                        chatToken = token
                    }
                }
                is ResponseResource.Failure -> {
                    handleTokenGenerationFailure.invoke()
                }
            }
        }
        return chatToken
    }

This is leading to generate ANR for some user. How can we make it asynchronous?
