Using scroll tomes on Switch

I’ve just started playing Diablo II: Resurrected on Nintendo Switch and can’t for the life of me work out how to use scrolls from the tomes. You have to equip a scroll to be able to use it and it won’t let you equip the tome, so there’s no way to use the scrolls stored in the tome as you can’t take them out of the tome to use individually either. Hopefully someone can help me out here and tell me what I’m missing.
