I want to send a notification to Slack on Insert into the table. What is the best way to achieve this for a local SQL database? This throws an error Execution Timeout Expired. The timeout period elapsed prior to completion of the operation or the server is not responding.

USE [MYDB2021]
GO

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

CREATE TRIGGER [dbo].[mytrigger]
   ON  [dbo].[Doc_Header ] 
   AFTER INSERT,UPDATE
AS 
BEGIN
    -- SET NOCOUNT ON added to prevent extra result sets from
    -- interfering with SELECT statements.
    SET NOCOUNT ON;

    -- Insert statements for trigger here
    DECLARE @command VARCHAR(1000)
    SET @command = 'C:\notify.bat'
    EXEC master..xp_cmdshell @command 

END

The Notify.bat file runs a js file to send a notification to slack

@echo OFF
start cmd /k "node C:\slack.js"
