I'll personally experience from any time and space (time in society and specific society) of my choosing, a fate that is generally considered worse than death or one of the worst things that can be done to person, this fate or thing that can be done will also be chosen by me, I will also experience it as the victim themselves, I will feel every sensation they felt by the victims etc. I will do this multiple times if needed. Or I can do something like i experience the fate instead of the victim, making me the victim instead of the original recipient (still choosing the fate of course), in which it can be seen as me saving them, anyway after I experience the fate I will be restored or brought back to the omnipotent.
Or I will receive multiple mental trauma, issues, disease etc of my choosing, and I will live with them for the least amount of time required, the trauma will also be removed from the victims as I take them on.
Or if given a few powers of my choice, I will bring humanity or any sentient species to a peak of technological progress,medical health, education, low crime rate, low to no poverty etc. or if given those powers of my choice, I'll create a country with 0 crime rate and 0 poverty and it'll simply peak in majority if not all categories, maybe, I'll even say it'll become a world power while it.
Or if given powers of my choice I will build the best civilization from the ground up, starting from it's very evolution into a sentient species etc, if I manage to get them as far as possible or further than any other civilization in the universe then I win.
I will keep giving them offers and offers or convince them other ways.
