Custom background dark mode / light mode solved

Hi after searching without success.. I wanted to share with you how to tell iPhone to change custom background in light mode and dark mode.

I just used shortcuts commands and tell iPhone to set a custom background in two separate folders called light mode and dark mode.

The first command changes background at 6 am

The second command at 6 pm

to change background simply replace the images with new ones 😊

I hope I helped others who searched for this like me.
