Spark AR studio, get position of object in v100+

I am super lost in the jungle that is the documentation of SparkAR. I am trying to get the coordinates of a plane inside of the script editor, to use in collider detection, but I can't seem to get the right results. I need a 2d vector output with the x and the y axis, but all documentation I could find was in lower versions. I am able to get the x position of an obejct using:

plane4.worldTransform.x.monitor().subscribe(function (posX) {
  Diagnostics.log(posX.newValue);
});

But this only prints the x value and I want to use the coordinates inside of the Patch Editor using From Script. Anybody that can help me with this, is greatly appreciated.
