[USUM] Anyone has a list of story related flags?

[Lunos]

Hi.

I need to check if multi battles triggered during the story in newer Pokémon games have custom text strings when the Player and their partner lose.

I see there's a battle with Hau against some Team Skull grunts in Diglett's Tunnel, but I probably already completed that event in my main savefile (which I haven't touched in some time, to the point that I barely remember the events of the story because I don't think I liked the game), so I'd like to know if perhaps someone around here knows which flag or flags that event uses, so I can unset/clear them using PkHex and then repeat that event.

Thanks!
