Opposite of TransformCoordinates

Questions
1

I know that it is a silly question, but I can not find out the answer.
Starting from the ‘Satellite’ example Transform Coordinates - Babylon.js Documentation
if I have this code :
var matrix = box.getWorldMatrix();
var local_pos = new BABYLON.Vector3(0, 1, 0);
satMesh.position = BABYLON.Vector3.TransformCoordinates(local_pos, matrix);

if I know the ‘satMesh.Position’, how can I get the position in the box local coordinate?

TIA

console.log(satMesh.position) gives the position relative to the box local axes.

console.log(satMesh.getAbsolutePosition()) gives the position in world coordinates

Alternatively, you can invert the matrix
matrix.invert() (in place)
or
matrix.clone().invert()

@Gijs thanks, this is what I was searching for
