Here are a few suggestions:

1. There should be some distance between the Add Games button in the lower right corner and the corner of the screen, maybe 5-20px is good.
2. When clicking the Add Games button to start retrieving all the apps, which can cause lag on some devices, you can usually add a "loading" prompt message, or you can also retrieve the apps in the background when you open them or after you open them, which has a significant effect on increasing the user experience.
3. The description and buttons in the setup should be sorted close to the screen respectively, e.g. the buttons are sorted to the right, rather than following the description.
4. If there are new strings that need to be translated please @we so we know you need our help, after all we can't keep an eye on your project all the time.
