When Toneri was draining chakra from Naruto, Hinata used her own to replenish/mix with Naruto's, preventing Toneri from draining anymore - for whatever reason, he couldn't drain Hamura's chakra, when at the start of the movie he drained Hinata's chakra entirely (before she met Hamura). As well as using it to destroy the Tenseigan Energy Vessel before that, with some help from Naruto

Hinata even said that Hamura's chakra flows within her when questioned about how from Toneri- it shows well, considering that it changed her Twin Lion Fists color from blue to purple - Sasuke had a similar thing happen to his Chidori when channeling his half of Hagoromo's power/chakra

^As far as descendant though, that's about as far as any Hyuga being descended from the Otsutsuki clan; there's no proof it was anything more direct. Even Hamura's title of Byakugan Princess seemed to be because her chakra was pure - 'simply' because of that fact, rather than anything truly special. Or least that's how I saw it
