How can I check if an object has entered a trigger with a script attached to a different object?

If I have the player walk into something that is a trigger with a certain tag, how can I set a boolean to true and check that it’s true with a script attached to a different object?

public class Player : MonoBehaviour
{
public bool EnteredTrigger;

    public void OnTriggerEnter(Collider other)
    {
        if (other.tag == /*the tag*/)
            EnteredTrigger = true;
    }
}

public class OtherScript : MonoBehaviour
{
    private GameObject m_Player;
    private void Start()
    {
        m_Player = GameObject.FindWithTag("Player");
    }

    private void Update()
    {
        if (m_Player.GetComponent<Player>().EnteredTrigger)
            //Do whatever
    }
}
