How would I go about using the shader graph to create a transparent material that catches and shows shadows?

I have been using a plane with a shader that is transparent but catches shadows in all of my AR projects so far. I've moved on to using the Universal render pipeline and the shader I would normally use doesn't work. The shader graph seems like it should hold the answer to this problem, but I don't know which nodes to use to replicate the effect. Any help would be greatly appreciated. Thank you in advance!
