❔ Unity clamp rotation

hello, i need to limit a rotation relative to another rotation and i don't know how to do it, i've already tried a lot of things. i need something like

float angle = Mathf.Clamp(target.rotation.x, reference.rotation.x-maxAngle, reference.rotation.x+maxAngle);

float angle = Mathf.Clamp(target.rotation.x, reference.rotation.x-maxAngle, reference.rotation.x+maxAngle);

but there are always problems with quaternoins.

public Transform target;
    public Transform reference;
    public Vector2 maxAngle = new Vector2(30f, 30f);
    public Vector2 targetAngle = new Vector2(30f, 30f);

    void Update()
    {
        Vector3 clampedAngle = new Vector3(targetAngle.x, targetAngle.y, 0);

        float a = Vector3.SignedAngle(reference.forward, Quaternion.Euler(targetAngle) * Vector3.forward, reference.right);

        float inverseX = reference.eulerAngles.x < 0 ? -1 : 1;
        float inverseY = reference.eulerAngles.y < 0 ? 1 : -1;

        float inverseXDist = WrapAngle(Mathf.Abs(a)) >= 90f ? -1 : 1;
        float inverseXRot = WrapAngle(Mathf.Abs(a)) >= 90f ? -180 + maxAngle.x * 2 : 0;
        float inverseXRot2 = WrapAngle(Mathf.Abs(a)) >= 90f ? -180 : 0;

        float x = Mathf.Clamp(WrapAngle(clampedAngle.x), WrapAngle(-maxAngle.x + Mathf.Abs(reference.eulerAngles.x) * inverseXDist + inverseXRot2), WrapAngle(maxAngle.x + Mathf.Abs(reference.eulerAngles.x)) * inverseXDist + inverseXRot);
        float y = Mathf.Clamp(WrapAngle(clampedAngle.y), WrapAngle(-maxAngle.y - Mathf.Abs(reference.eulerAngles.y) * inverseY), WrapAngle(maxAngle.y + Mathf.Abs(reference.eulerAngles.y)));
        target.rotation = Quaternion.Euler(x, y, 0);
    }

    public float WrapAngle(float angle)
    {
        angle = angle % 360f;
        if (angle < -180f)
            return angle + 360f;
        else if (angle > 180f)
            return angle - 360f;
        else
            return angle;
    }

public Transform target;
    public Transform reference;
    public Vector2 maxAngle = new Vector2(30f, 30f);
    public Vector2 targetAngle = new Vector2(30f, 30f);

    void Update()
    {
        Vector3 clampedAngle = new Vector3(targetAngle.x, targetAngle.y, 0);

        float a = Vector3.SignedAngle(reference.forward, Quaternion.Euler(targetAngle) * Vector3.forward, reference.right);

        float inverseX = reference.eulerAngles.x < 0 ? -1 : 1;
        float inverseY = reference.eulerAngles.y < 0 ? 1 : -1;

        float inverseXDist = WrapAngle(Mathf.Abs(a)) >= 90f ? -1 : 1;
        float inverseXRot = WrapAngle(Mathf.Abs(a)) >= 90f ? -180 + maxAngle.x * 2 : 0;
        float inverseXRot2 = WrapAngle(Mathf.Abs(a)) >= 90f ? -180 : 0;

        float x = Mathf.Clamp(WrapAngle(clampedAngle.x), WrapAngle(-maxAngle.x + Mathf.Abs(reference.eulerAngles.x) * inverseXDist + inverseXRot2), WrapAngle(maxAngle.x + Mathf.Abs(reference.eulerAngles.x)) * inverseXDist + inverseXRot);
        float y = Mathf.Clamp(WrapAngle(clampedAngle.y), WrapAngle(-maxAngle.y - Mathf.Abs(reference.eulerAngles.y) * inverseY), WrapAngle(maxAngle.y + Mathf.Abs(reference.eulerAngles.y)));
        target.rotation = Quaternion.Euler(x, y, 0);
    }

    public float WrapAngle(float angle)
    {
        angle = angle % 360f;
        if (angle < -180f)
            return angle + 360f;
        else if (angle > 180f)
            return angle - 360f;
        else
            return angle;
    }

I tried to fix it but nothing worked for me. only u works well
