How do I configure a wait before running the launch command?

I have a straightforward launch command: npm run dev but my terminal doesn't start fast enough for the debugger, so it executes the command before my shell is ready. This means I always have to manually run the command after to get it to work. Is there a way I can setup the launch task to wait like 500ms or something before running the command?

Launch.json:

{
  "configurations": [
  {
      "name": "Next.js: debug full stack",
      "type": "node-terminal",
      "request": "launch",
      "command": "npm run dev",
      "internalConsoleOptions": "openOnSessionStart",
      "serverReadyAction": {
        "pattern": "- Local:.+(https?://.+)",
        "uriFormat": "%s",
        "action": "debugWithChrome",
      },
    }
  ]
}

Terminal output:

npm run dev
 ~/W/p//boarder  BETA-138-Occ…cle-presence *1 !8 ?1 
❯              

Start with the launch.json configuration and the node-terminal launch path that runs npm run dev; determine whether command startup timing is configurable there. Done means establishing a clear supported behavior for delaying the launch command and documenting or validating the requested 500ms-style use case.
