script to determine whether to get the flag, run success or failure.

public class IsHasFlag :Conditional {
    private Offense offense;
    public override void OnAwake()
    {
        offense = this.GetComponent<Offense>();
    }
    public override TaskStatus OnUpdate()
    {
        if (offense.hasFlag)
        {
            return TaskStatus.Success;
        }
        return TaskStatus.Failure;
    }
}

Add banner above script to determine whether the tag is a collision of players, to collision of a boll value, and let the flag collision coordinate equal players, with a look to make the flag go

   private Offense owner;
    public void OnTriggerEnter(Collider other)
    {
        if (other.tag == "Offense")
        {
            if (owner != null)
            {
                owner.hasFlag = false;
            }
            other.GetComponent<Offense>().hasFlag = true;
            transform.parent = other.transform;
            owner = other.GetComponent<Offense>();

        }
    }
}
