Kaguya ate the God Tree's chakra fruit as a whole, while usually Ootsutsuki clan members (like Momoshiki) proceed to harvest this fruit and turn it into pills to consume them afterwards. Both the fruit as a whole and pills grant Ootsutsuki chakra, so Kaguya obviously wasn't the first of her clan to wield it, she just achieved it by untraditional means.

Exactly
Kaguya was a greedy girl, she didn't want to share them dragon ball fruit to anybody.
That fruit is the same as the pills, the pills are smaller version, me thinks.
It also seems that these aliens can also make the same Trees that boar these fruits from Tailed beast Chakra. So, maybe... Just maybe, the Chakra Fruit wasn't meant to be eaten or turned into pills but to grow other trees, so to spare all the long searches for them.
Well, since Momoshiki turned Bee's Tailed Beast chakra into pills, I guess, the pills allowed him to plant a new God Tree on Momoshiki's Planet. Since the pills are usually made from the chakra fruit, it can be presumed that Ootsutsuki can use it to sustain their youth and powers and to grow more trees at the same time.
