Change category and group type from "Income" to "Expense"

I am just setting up Monarch for the first time and added a new category group for Petcare, with a few categories beneath, but accidentally added it under Income rather than Expenses.

I'm trying to change the categories/groups to Expense but am not seeing how to do so. A few posts have said that you're able to change the type in the mobile app but I don't see it. I also don't see it on desktop/web. I also tried dragging the group from Income > Expense but it doesn't allow the drag.

Just want to triple check there isn't something I'm missing before I manually move everything to new categories!

Thanks.
