Fully Kiosk Browser On Samsung Tablet Tab S8 Ultra - Cannot get Screen lock to work when using

just installed Fully Kiosk Browser last night and cannot find how I can still keep my lockscreen working when using this xdrip+ software. I normally can keep a USB charger in Samsung Tablet press the power button click on the Samsungs Tablet screen and it shows my clock and medical readings on my screen for seeing during the night.

But as soon as I start to use Fully Kiosk Browser it prevents it from working.

I have turned off Keep Screen On in the settings but it’s still not working anyone have any clues on what settings I need to turn off in Fully Kiosk Browser or on the Samsung Galaxy Tab S8 Ultra
