Microsoft Edge Game Assist is a feature in Microsoft Game Bar that allows users to quickly and easily open the Microsoft Edge web browser in games. This feature was initially introduced in the Microsoft Insider Program first, but has now been introduced in the stable version.
To enable it, you just need to open the Microsoft Edge web browser, go to the Settings menu, search for the Game Assist feature in the search bar, and enable the feature from there. Once done, you can activate the Game Bar menu with the Windows key + G shortcut.
You will see the Microsoft Edge web browser in the Game Bar menu, and you can use it to access various gaming websites for help such as walkthroughs and so on.
You just need to update the Microsoft Edge web browser to Stable version 132 to access this feature.
