Launch a new tab in the existing/running Chrome instance

I have an instance of Chrome running with remote debugging enabled. I would like VS Code to launch a new tab (and/or window) in this instance and attach the debugger to it.

As far as I understand, the attach task is not what I need here, because this is intended for attaching to an existing tab.

I have tried using a launch task but it doesn't seem to open a new tab. Instead, it will navigate to url in the most recent tab, and then open a new blank tab.

{
    "type": "pwa-chrome",
    "request": "launch",
    "name": "Launch Chrome (existing)",
    "url": "http://localhost:5000",
    "webRoot": "${workspaceRoot}",
    // By default, the extension launches Chrome with a separate user profile in a temp folder. We
    // set it to `false` to launch with the default user profile instead, so we don't have to
    // reinstall extensions like React dev tools and re-configure any preferences.
    "userDataDir": false,
    "port": 9222
}

Is there a way to make it open a new tab instead?
