1. It has been shown that powers amongst members of the Otsotsuki clan are basically split evenly between siblings. Examples include Haguromo and Hamura each receiving one of Kaguya's dojutsu and Haguromo's Rinnegan being essentially split in half between Asura and Indra.

2. Naruto and Sasuke both possess the transmigrate chakra of their ancestors, Asura and Indra.

3. By combining in his descendants the chakra of the sibling of whom they were not a transmigrate, Haguromo instills within them new powers, including flight, chakra restoration, a functioning Rinnegan, and teleportation. This implies that as the original bearer of this particular chakra set, Haguromo possessed all of these abilities.

4. This further implies that Kaguya, progenitor of chakra in general an the chakra of her son's specifically, had access to all of their powers, including teleportation (as well as the power of will materialisation, which has not appeared as a confirmed power of the brothers and therefore may exist as an exception to this process).

Again, I do not know for sure who asked the question, but here is a reasonable (I.e. not Hamura=Uzumaki=Zetsu) answer using evidence found in the manga, along with some supported inferences, as to why Kaguya can teleport. What this teleportation actually entails is another question, and one whose answer eludes me.

there is a simpler explanation

Kaguya had already been shown to transport them to another dimension. she could have simply stepped outside of said dimension and stepped back in on the other side
