How to get or inject dependencies in custom action classes? We can do GameObject.GetComponent OnStart but that will get every time the node starts. Instead of initializing one time.

Current work around

[SerializeReference] public AIMovementHandler aiMovementHandler;

protected override Status OnStart()
{
    if(aiMovementHandler == null)
        aiMovementHandler = GameObject.GetComponent<AIMovementHandler>();
    
    
    Debug.Log("on start of node");
    aiMovementHandler.SetDestinationToChild();
    return Status.Running;
}

There is unneccessary null check every time the node executes

Is there nothing like Awake or constructor where i can initialize it just once.
