How to smoothly rotate an object (code doesn't work)?

Question

Unity

It is necessary to smoothly rotate the object along the x-axis (horizontal) by pressing the button.

Here's a working code that will sharply rotate an object.

public void RotateIt()
{
GameObject imageCharacter = GameObject.Find("Image-Character");
imageCharacter.transform.rotation = Quaternion.Euler(0, 180, 0);  // Резкий поворот. Работает.
}

Here's a gentle twist

public void RotateIt()
{
GameObject imageCharacter = GameObject.Find("Image-Character");
imageCharacter.transform.rotation = Quaternion.Lerp(transform.rotation, Quaternion.Euler(0, 180, 0), Time.deltaTime); // Плавный поворот. Не работает.
}

Smooth turn code with no syntax errors, but nothing happens when the button is clicked.

But it is necessary in Updateand not just like that. You also need to be able to copy examples.
