Crouch action does not work properly

[sanketsans]

I looked into the game file, it says 2 acts for crouch movement. But when I create the environment, it does not crouch - just stand still. Also, 0 make the dino jump instead of just running.

env = gym.make('ChromeDino-v0')

env = make_dino(env, timer=True, frame_stack=True)
state = env.reset()
done = False
score = 0
while True:
#     action = np.random.choice(np.arange(1,4))
    action = 2
    state, reward, done, _ = env.step(action)
    score += reward
    if done:
        state = env.reset()
