How to match the local y-axis direction of the ImageTarget with the normal direction of the ground plane

Question

I can't create a physical scene on EasyAR because I don't know how  to match the local y-axis direction of the ImageTarget with the normal direction of the ground plane.

Even if the ImageTarget is rotated by 90 degrees with the transform.x 90 degrees,  the parameter is reset immediately after startup.

Please tell how to solve this problem.
