Screen dim in automation real device 15.1

When I use the Appium with Real deviec in Ios 15.1 there is overlay, meanwhile the automation is runing, the screen dimms , is there option that the screen will stay awake and in full light all the tests?
Thank you

No way. This is only visible to you. If you record screen it will be without overlay on video.

@Aleksei I know that there is overlay, the question is just on the dim / brightness of the screen if there is option to let it be on the maximum when tests is runing?
