My personal opinion on this is that, since the tree Obito created was shown to have the eye of the Ten Tails, Rinne-Sharingan, Madara had to absorb the tree to be even able to gain the potential for it to manifest. Then, by taking back his left eye, he regained the full power of his Rinnegan, since Dojutsu work best when together as a pair, and by approaching the moon which Kaguya was trapped in for centuries, her chakra was able to be called into his body by Ten Tails, just enough for the Rinne-Sharingan to manifest. And, after the IT was cast, all the people of the world were linked by the Shinju, all of their chakras were combined to recreate enough of Kaguya's for Black Zetsu to revive her using the Ten Tails, the Shinju, which gave her the power she had, as a template in a way, her chakra was reproduced in a large enough amount to take full possession of Madara with Black Zetsu's body which was also a part of her chakra to call back her personality or soul if you will. Just my theory, feel free to disagree
