If I was Kishimoto, this is how I would write this scene.
Naruto thinks to himself about how to stop Kaguya, minus the space taking flashback panels. Kaguya floats there and suddenly dashes toward him, however, her speed is too great to react to and Naruto was not done devising his plan. Kaguya grabs Naruto's head and begins to absorb his chakra, paralyzing him. She now announces that this her her dimension and he is powerless here. Seeing as his main body is in trouble, Naruto's clone goes to distract Kaguya, trying to attack her, but she blocks his attacks with her vaccum fists with her free hand. While Naruto's clone preoccupies Kaguya, Obito uses Kamui to sever Kaguya's arm that was absorbing Naruto's chakra. Naruto, now freed from her influence, breaks from the ice with boil release and delivers a powerful blow to Kaguya sending her crashing into the ice wall. He then creates an army of clones and announces that this is now his dimension. Kaguya arises from the wall and regenerates her arm, it continues normally from then on.
