ARCore How to replace the detected plane to custom 3d model in Unity

问题

I'm really new to the ArCore, can anyone guide me on how to replace or change the detected plane object to that model what I want to display.

What I'm trying to do is when the app is launched, we scan the ground and instead of a plane I want to show the shaded version of my model, and once I tap on the screen I want to place the actual model.

I'm trying to do this with UNITY in ARCore.

Can anyone help me with this?
