Change classes for my custom dataset

[Theodore-xs]

I have generated labels_with_ids for my custom dataset like below . But I am confused about how to change the meaning of each class_id label.
For the original work , there are 5 classes or 10 classes representing A , B ,C ......
But I want 2 classes representing X , Y different from original objects' meanings. So where should I change?
