Clarification on AIR-v0-SB3 Task and air_env_rl Usage

[yYang-bit]

Hi,

Thank you for your open-source contribution — we are trying to use MetaIsaacGrasp for our own robot and making some modifications.
After applying the code, I have some questions:

1. When I run --Task AIR-v0-SB3, I encounter an error in MetaIsaacGrasp/isaac_env/air_env_sb3/init.py at:
   gym.register(
   id="AIR-v0-SB3",
   # entry_point="isaaclab.envs:ManagerBasedRLEnv",
   entry_point="isaac_env.air_env_rl:AIREnvSB3",
   kwargs={
   "env_cfg_entry_point": CellEnvCfg,
   "sb3_cfg_entry_point": f"{agents.name}:sb3_ppo_cfg.yaml",
   "rl_games_cfg_entry_point": f"{agents.name}:rl_games_ppo_cfg.yaml",
   },
   )
   Should "isaac_env.air_env_rl:AIREnvSB3" be changed to "isaac_env.air_env_sb3:AIREnvSB3"?

2. The README does not mention air_env_rl. Is this part usable?

3. If I want to apply the environment to my own robot (changing USD and part of the observation space), should I be using --Task AIR-v0-RL instead?

Your clarification would be very helpful.
Thank you!
