Pocahontas had one child, Thomas Rolfe, whose father was an Englishman. The son married an Englishwoman in the colonies.
Given that, I'd be curious to know by what measure this woman claims to be a 'descendant' of Pocahontas in the context of having Native American ancestry connected directly to Pocahontas.
Pocahontas moved to England and changed her name to Rebecca Rolfe. She never returned to the colonies. She lived and died as a proper Englishwoman.
So strictly speaking the woman in the OP would not be a descendant of Pocahontas.
Strictly speaking, loosely speaking, the woman in the OP could safely be said NOT to be a descendant of Rebecca Rolfe, nee Pocahontas.
She might be a descendant of the Algonquin Indians known as Powahatan (erroneously attributed as the father of Pocahontas.
The error might be from Wikipedia that states that the Rolfe's were one of the first Families of Virginia and Thomas married and made his home there. This is untrue. Alexander Whittaker converted Pocahontas to Christianity and baptised her as Rebecca. She married tobacco planter, John Rolfe. Rebecca was invited to England to meet the Queen as an example of civilized Christianity. She and her husband and young son, Thomas traveled to England where they lived for two years. The family was plannning a return trip to the colonies when Rebecca sickened and died in Kent, of the consumpition. She was buried as a property Englishwoman. Thomas was sent to live with his Uncle Henry in Plymouth England. He did not return to Virginia until 1641. While Thomas did marry, it was to an Englishwoman. They had one child, a daughter who married an Englishman, John Bolling. There was no continuation of Native lineage. In fact, Thomas Rolfe, as a Lieutenant fought against the Natives in various campaigns. There is simply no basis on which any one today named White Dove can claim to be a direct descendant of Pocahontas.
