Compiling some initial issues with the new Typescript (v4) chat client

#2

First off great to see Sendbird moving to first class Typescript support!

We are running into some initial issues around creating a type safe client with the new module system.

let sendbirdChat: SendbirdChat; 

const init = () => {
  if (!sendbirdChat) {
    sendbirdChat = SendbirdChat.init({
      appId: 'APP_ID',
      localCacheEnabled: true,
      modules: [new GroupChannelModule()],
      useAsyncStorageStore: AsyncStorage,
    });
  }

  return sendbirdChat;
};

// @ts-expect-error Property 'groupChannel' does not exist on type 'SendbirdChat'
sendbirdChat.groupChannel

Any suggestions for how to create a type safe client that uses modules?

We could work around this if ModuleNamespaces and Modules types were exposed publicly

Less urgent but the type definition for AsyncStorageStatic is incompatible with @react-native-async-storage/async-storage

    Types of property 'getItem' are incompatible.
      Type '(key: string, callback?: CallbackWithResult<string> | undefined) => Promise<string | null>' is not assignable to type '(key: string, callback?: ((error?: Error | undefined, result?: string | undefined) => void) | undefined) => Promise<string | null>'.
        Types of parameters 'callback' and 'callback' are incompatible.
          Types of parameters 'error' and 'error' are incompatible.
            Type 'Error | null | undefined' is not assignable to type 'Error | undefined'.
              Type 'null' is not assignable to type 'Error | undefined'.ts(2322)
__definition.d.ts(868, 3): The expected type comes from property 'useAsyncStorageStore' which is declared here on type 'SendbirdChatParams<GroupChannelModule[]>'
