How to use the @ckeditor/ckeditor5-engine/src/model/selection.createFromSelection function in @ckeditor/ckeditor5-engine

_getObjectElementNextToSelection( forward ) {
		const modelDocument = this.editor.document;
		const schema = modelDocument.schema;
		const modelSelection = modelDocument.selection;
		const dataController = this.editor.data;

		// Clone current selection to use it as a probe. We must leave default selection as it is so it can return
		// to its current state after undo.
		const probe = ModelSelection.createFromSelection( modelSelection );
		dataController.modifySelection( probe, { direction: forward ? 'forward' : 'backward' } );
		const objectElement = forward ? probe.focus.nodeBefore : probe.focus.nodeAfter;

		if ( objectElement instanceof ModelElement && schema.objects.has( objectElement.name ) ) {
			return objectElement;
		}

		return null;
	}
}
