Oh it seem you doesnt really know about Kaguya's S/T jutsus
Amenominaka
Using her third eye, Kaguya is able to instantly teleport herself, and anyone within a certain range of her, to different dimensions. Those affected by it are caught completely off guard, as there seems to be no warning prior to its usage and have found themselves plunging into a river of lava,[2] and abruptly being encased within a block of ice.[3] Having been sent to a different dimension, the presence of their chakra is completely erased in the normal world and cannot be sensed through traditional means.[4]
Kakashi states that Kaguya has the ability to instantly rewrite all aspects of the dimension, a phenomenon he also compares to the creation of genjutsu.[5] Doing so, however, was noted to be very chakra taxing.[6]
Databook translation
Kaguya's dimensional swap technique:
Amenominaka:
A jutsu used by Kaguya with her "Rinnesharingan". Changes the world around the user and the people around her into another dimension. The dimensions it can move to are ones of lava, ice, gravity, sand, and acid, and these five dimensions are directly linked to (whatever dimension Black Zetsu mentions back when Naruto is there with them. I can't remember or figure out how to translate it). Using it consumes a huge amount of chakra, making it an eye jutsu only she can use.
Kanji: Heaven, Govern/Control, Inside
Here is how Amenominaka works. No portal, she just changing dimension.

Yomotsu Hirasaka
The user is able to form rifts within the fabric of space that allows them to instantaneously transport themselves to different locations. They are also capable of sending different sections of their body forth by partially entering through the portal. Furthermore, they can use the portal to catch the enemies off guard by creating rifts behind them, and sending them to different dimensions. This happens so quickly that even Sasuke Uchiha was unable to evade it.[2] It has been shown, however, that evading the portals is possible.[3]
Databook Translation
Kaguya's portal ability: Yomotsuhirasaga (黄泉比良坂), named after the slope that leads to the underworld in Japanese mythology; the section header calls it a "gateway to the underworld" (冥府の門口). It allows her to create an opening in space through which she can freely enter and exit any of her six dimensions, and it could be said that this technique was the original (元祖, original, founding, pioneering) space-time ninjutsu. It goes on to describe it as being similar to kamui in that it can be used to trap enemies, for transportation, and so forth (all the things we say Kaguya doing with it).
