+    \qmlmethod void QQuick3DXrSpatialAnchorListModel::requestSceneCapture()
+    \brief  This method triggers a scan to capture or update spatial data for the current environment.
+
+    This method triggers the underlying XR system to perform a scene capture of the user's current physical environment,
+    to update or refine the spatial mesh, enabling more accurate placement and tracking of spatial anchors.
+
+    \note Some platforms do not perform this operation automatically.
+    For example, on Quest 3, if the user is in a previously uncaptured space, this method will not be called automatically,
+    resulting in no available anchors until a capture is manually triggered.
