How to disable popup happening on edge 118?

I spent a lot of time figuring this out today and finally found a solution, add the `--guest` argument.   The `no-first-run` switch worked but presented a Welcome Screen overlay.

The browser will use a default Guest profile, which doesn't prompt for profile changes.

NodeJS example (used with WebdriverIO v7)

capabilities = {
    browserName: 'MicrosoftEdge',
    acceptInsecureCerts: true,
   'ms:edgeOptions': {
        args: ['test-type', '--no-sandbox', '--disable-dev-shm-usage', '--guest'],
        excludeSwitches: ["enable-automation", "no-default-browser-check"]
    }
}
