How to show previews left and right using ViewPager2

I searched in SO but most of them are ViewPager(s). Some are ViewPager2(s) but written in kotlin. Could you show me the code to implement left-right preview in ViewPager2? None of the things I've tried so far works.

        Intro_pager.setOffscreenPageLimit(2);
        Intro_pager.setClipToPadding(false);
        Intro_pager.setClipChildren(false);

        Intro_pager.setPageTransformer(new MarginPageTransformer(1500));
