I'd like to set the thumbnail image for an Xcode bot.
The project has a complete .appiconset folder for iPhone icons and these are shown on a device home screen when the application is installed. I assumed the bot would pull images from here but it appears not.
What I've tried
- Adding all other icon sets, including Mac, Watch and iPad.
- Adding the icon to the project as a separate .png file and referencing it within the info plist using the
CFBundleIconskey.

We cannot update the image from the Xcode. The image which is getting displayed is the data which is stored in "webui-optimized.css". If you need it specifically you can change the image data there.
the file location will be at "/Applications/Xcode.app/Contents/Developer/usr/share/xcs/xcswebui/webui/stylesheets/webui-optimized.css"
