Number of particles based on score collected?

Hi, in my 2D game player collect ,coins" and they count of how many has been collected. I want particles flying around the player, but only the number of how many has been collected. So if player collects 7 coins, then 7 coins will be flying around the player. Is it possible? if so, can you help me with the code? I’m code newbie. I know I need to somehow mention (already created and set) particle system in the script and somehow mention and change the Rate Over Time. But I have absolutely no idea how.

Score counter:

public class ScoreManager : MonoBehaviour
{
    public static ScoreManager instance;
    public TextMeshProUGUI text;
    int score;

    // Start is called before the first frame update
    void Start()
    {
      if(instance == null)
        {
            instance = this;
        }
    }

    public void ChangeScore(int coinValue)
    {
        score += coinValue;
        text.text = score.ToString();
    }
}

Nevermind. Got it. For anyone in the future(script below). Just assing the particle system in inspector and set Rate over time to 0.

public class ScoreManager : MonoBehaviour
{
    public static ScoreManager instance;
    public TextMeshProUGUI text;
    int score;
    public ParticleSystem par;

    // Start is called before the first frame update
    void Start()
    {
      if(instance == null)
        {
            instance = this;
        }

       

    }

    public void ChangeScore(int coinValue)
    {
        score += coinValue;
        text.text = score.ToString();
        var emission = par.emission;
        emission.rateOverTime = score;
    }
}
