Android Page not refresh using adapter.refresh() in RxPagingSource

Question

1. DataSource extends RxPagingSource

    @NotNull
        @Override
        public Single<LoadResult<Integer, L>> loadSingle(@NotNull LoadParams<Integer> params) {
            nextPageNumber = params.getKey();
            if (nextPageNumber == null) {
                nextPageNumber = 1;
            }
    
            return getApiRequest(nextPageNumber, params.getLoadSize())
                    .subscribeOn(Schedulers.io())
                    .map(d -> toLoadResult(params, d))
                    .onErrorReturn(LoadResult.Error::new);
        }
    

protected LoadResult<Integer, L> toLoadResult(LoadParams<Integer> params, D response) {}

2. Handle datasource in ViewModel

    Flowable<PagingData<PojoPassengerData>> flowable = PagingRx.getFlowable(
                        new Pager<>(new PagingConfig(TOTAL_PAGES), () -> new FakeTestSource(mApiService)));
                PagingRx.cachedIn(flowable, viewModelScope);
    
                mCompositeDisposable.add(
                        flowable.subscribe(pagingData -> dataPagingData = pagingData));

3. Handle in Fragment

     adapter.submitData(getViewLifeCycle(), mViewModel.dataPagingData);

4. Not refresh data by called here

    private void onRefresh() {
            mViewModel.showSwipeRefresh();
            adapter.refresh();
        }

I'm using Paging3 (3.0.1 Latest) and setup with Recycler view.

Load more working Retry working (with is called as adapter.retry() )

NOTE: Setup paging in RxJava so comment based on that.

Thanks in advance.
