I have a problem with 2d Colliders or triggers (or both)

Questions & Answers
1

I am developing a simple 2D platform game with a minigame between levels (cause I started to learn Unity and C# just 4 months ago). The idea is that when the player approach certain object, a text appears telling that he has to press E to do the mini game. I am using OnTriggerStay2D, but it not always works, That is to say, the player enter de collider of the object, the text appear, but I press E and nothing happens, but if I try many times, at the end sometimes works and the mini game scene is loaded.

This is the code I am using:

public class Door1 : MonoBehaviour
{
public GameObject switchButton;
public GameObject door1Text;
public AudioSource test1Voice;

void Start()
{
    door1Text.SetActive(false);
    switchButton.SetActive(false);
}

private void OnTriggerStay2D(Collider2D player)
{
    if (player.gameObject.CompareTag("Player"))
    {
        door1Text.SetActive(true);
        switchButton.SetActive(true);
        test1Voice.Play();
    }

    if (Input.GetKeyDown(KeyCode.E))
    {
        SceneManager.LoadScene("Neologism1");
    }
}

private void OnTriggerExit2D(Collider2D player)
{
    if (player.gameObject.CompareTag("Player"))
    {
        door1Text.SetActive(false);
        switchButton.SetActive(false);
        test1Voice.Stop();
    }
}

This is the exact moment:

The player has a circle collider 2d, cuz de box colider cause me some problems with the movement (the player use to get stopped frequently).
If someone could give me a tip of what is happening I would be very grateful.

Anyway, thanks in adcanced to everyone.

OnTriggerStay() Does not update every frame but rather a fixed amount of seconds, Input.GetKeyDown() Activates the one frame when pressed down, so the only time it would work if the ontriggerstay updates the same frame the button is pressed.

it is always better to keep GetKeyDown inside An update function.

    bool IsPlayInsideArea = false;

    void Start()
    {
        door1Text.SetActive(false);
        switchButton.SetActive(false);
    }

    private void Update()
    {
        if (Input.GetKeyDown(KeyCode.E) && IsPlayInsideArea)
        {
            SceneManager.LoadScene("Neologism1");
        }
    }

    private void OnTriggerStay2D(Collider2D player)
    {
        if (player.gameObject.CompareTag("Player"))
        {
            door1Text.SetActive(true);
            switchButton.SetActive(true);
            test1Voice.Play();

            IsPlayInsideArea = true;
        }
        
    }
    private void OnTriggerExit2D(Collider2D player)
    {
        if (player.gameObject.CompareTag("Player"))
        {
            door1Text.SetActive(false);
            switchButton.SetActive(false);
            test1Voice.Stop();

            IsPlayInsideArea = false;

        }
    }
