How to listen for code deleted by developers? I cannot obtain the deleted code using the following API, but I obtain the code after deleting it

[zbsguilai]

vscode.workspace.onDidChangeTextDocument(async (event) => {
const document = event.document;
const contentChanges = event.contentChanges;

	for (const change of contentChanges) {
	  if (change.text === '') {
		await vscode.commands.executeCommand('workbench.action.files.save'); // 等待文档保存
  
		// 等待文档更新
		await new Promise((resolve) => setTimeout(resolve, 100));
  
		const deletedText = document.getText(change.range);
		console.log(`文件 ${document.fileName} 删除了文本：`);
		console.log(`被删除的文本内容：${deletedText}`);
		console.log(`范围：${change.range.start.line}:${change.range.start.character} - ${change.range.end.line}:${change.range.end.character}`);
	  }
	}
  })
)
