Question Is there really no equivalent GVRreticle pointer for XR system... still?

It has been about a year since XR plugin launched and since then I have had to stay on an old version of unity as I use the GVRreticlepointer throughout my app. I would obviously like to replace this with the new XR unity system. Despite lots of searching (my original question on this back in May 2020 comes up top of the search results without any resolution) I still can't find a tutorial or code that does what the old system does.

Please can someone point me in the right direction
thanks
