You must have something wrong in your code:

with this code:

var delayCreateScene = function () {
    var scene = new BABYLON.Scene(engine);

    const getParentSize = parent => {
        const sizes = parent.getHierarchyBoundingVectors()
        const size = {
            x: sizes.max.x - sizes.min.x,
            y: sizes.max.y - sizes.min.y,
            z: sizes.max.z - sizes.min.z
        }
        return size
    };

    // The first parameter can be used to specify which mesh to import. Here we import all meshes
    BABYLON.SceneLoader.Append("scenes/hochbeet/", "hochbeet.gltf", scene, function (newMeshes) {
        scene.createDefaultCameraOrLight(true);
        scene.activeCamera.attachControl(canvas, false);
        scene.activeCamera.alpha += Math.PI; // camera +180°

        let bv = scene.meshes[0].getHierarchyBoundingVectors();
        let sz = getParentSize(scene.meshes[0]);

        let box = new BABYLON.Mesh.CreateBox("box", 1, scene);
        let mat = new BABYLON.StandardMaterial("mat", scene);

        mat.alpha = 0;

        box.material = mat;

        box.scaling = new BABYLON.Vector3(sz.x, sz.y, sz.z);
        box.position = new BABYLON.Vector3((bv.min.x + bv.max.x) / 2, (bv.min.y + bv.max.y) / 2, (bv.min.z + bv.max.z) / 2);
        box.enableEdgesRendering();    
        box.edgesWidth = 40.0;
    });

    return scene;
}
