KubeSpawner object has no attribute group_overrides

What I want to do:
The specific problem I’m facing now is that I have two different GPU cards, such as a 4090 and a 3090, and I hope to allocate the 4090 to Group A and the 3090 to Group B. So, I’m going to use KubeSpawner’s group_overrides attribute to accomplish what I need.
Problem:
I followed the instructions in the KubeSpawner documentation and tried to use the ‘group_overrides’ attribute to solve my task, but encountered an error in the logs stating that this attribute doesn’t exist. However, I found that some other attributes from the KubeSpawner documentation do work, such as ‘node_selector’

Figure 1 shows the error from the code in Figure 2, while Figure 3 demonstrates the normally executing version.
