Redux Toolkit w TypeScript：如何打开 AsyncThunk 的类型

Question

I hava a action called getIndexingConfig

export const getIndexingConfig = createAsyncThunk(
  "settings/getIndexingConfig",
  async () => {
    const {
      indexingConfiguration,
      groupIndexingConfiguration
    } = await sdkClient.getIndexingConfiguration().promise();

    return {
      indexingMode: indexingConfiguration?.thingIndexingMode,
      groupIndexingMode: groupIndexingConfiguration?.thingGroupIndexingMode
    };
  }
);

The type of it is, according to TS compiler

const getIndexingConfig: AsyncThunk<
  {
    indexingMode: string | undefined;
    groupIndexingMode: string | undefined;
  },
  void,
  {}
>;

I wonder how I can get the return value's type from it. ie

 {
    indexingMode: string | undefined;
    groupIndexingMode: string | undefined;
  }

I try to use ReturnType<typeof getIndexingConfig> but it doesn't seem to unwrap the thunk to give me the return value's type.

export type ITSUnpackedPromiseLike<T> =
    T extends ITSResolvable<infer U> ? U :
        T
    ;

ITSUnpackedPromiseLike<ReturnType<typeof getIndexingConfig>>
