How to setup createAsyncThunk without dataparameter with typescript?

Hello everyone, currently I am builing my first webshop as mern-stack with typescript. My authentication system works, but now I want to write the dashboard. I am used to overgive no data in the findAll or getStats function because I want to get all, that means I don’t need to overgive Id or data. So in javascript I have set a " _" as parameter and that has worked in my first mern-stack, but typescript knows not the type. How I can write this in typescript ? Thanks for your help.
That is my slice:

export const getAllUser = createAsyncThunk<object, _, AsyncThunkConfig>('/user/findAll', async (_, thunkAPI)=>{
    try{
        const token = thunkAPI.getState().auth.user!.accessToken;
        return await userService.getAllUser(token);
    }catch (error:any) {
      const message =
        (error.response &&
          error.response.data &&
          error.response.data.message) ||
        error.message ||
        error.toString()
      return thunkAPI.rejectWithValue(message as string)
    }
})
export const getUserStats = createAsyncThunk<object, _, AsyncThunkConfig>('/user/stats', async (_, thunkAPI)=>{
  try{
      const token = thunkAPI.getState().auth.user!.accessToken;
      return await userService.getUserStats(token);
  }catch (error:any) {
    const message =
      (error.response &&
        error.response.data &&
        error.response.data.message) ||
      error.message ||
      error.toString()
    return thunkAPI.rejectWithValue(message as string)
  }
})

I passed in <object, any, AsyncThunkConfig>. I don’t know if that is the solution, but I get no error anymore.
