Hello all. I have a RemoteMediator Paging 3 compose. But my id is a unique string (for example “sj-8kjh76”) that I get from the server. How can I load new items using append?

val loadKey = when(loadType){
                LoadType.REFRESH -> 1
                LoadType.PREPEND -> return MediatorResult.Success(
                    endOfPaginationReached = true
                )
                LoadType.APPEND -> {
                     return MediatorResult.Success(
                            endOfPaginationReached = true
                        )

                    // You must explicitly check if the last item is null when
                    // appending, since passing null to networkService is only
                    // valid for initial load. If lastItem is null it means no
                    // items were loaded after the initial REFRESH and there are
                    // no more items to load.

                }
            }
