No detailed and accurate explanation or tutorial for InteractiveScene

I could not use interactive scene. It has the explanation:
```
"""
To select mobjects on screen, hold ctrl and move the mouse to highlight a region,
or just tap ctrl to select the mobject under the cursor.
Pressing command + t will toggle between modes where you either select top level
mobjects part of the scene, or low level pieces.
Hold 'g' to grab the selection and move it around
Hold 'h' to drag it constrained in the horizontal direction
Hold 'v' to drag it constrained in the vertical direction
Hold 't' to resize selection, adding 'shift' to resize with respect to a corner
Command + 'c' copies the ids of selections to clipboard
Command + 'v' will paste either:
- The copied mobject
- A Tex mobject based on copied LaTeX
- A Text mobject based on copied Text
Command + 'z' restores selection back to its original state
Command + 's' saves the selected mobjects to file
"""

```

That is not enough to let me know how to see the window and use my mouse and keyboard.

When i use this code:
```
class ABC(InteractiveScene):
def construct(self):
text = Text('ABC')
self.play(Write(text))
```
It says:
```
Media will be written to c:\beibi\a\media\. You can change this behavior with the --media_dir flag.

There are no scenes inside that module

```
But if i add "Scene", it will be strange.
```
class ABC(InteractiveScene, Scene):
def construct(self):
text = Text('ABC')
self.play(Write(text))
```
`Media will be written to c:\beibi\a\media\. You can change this behavior with the --media_dir flag.
`
And then a window is displayed, but it disappears in an instant. Nothing is displayed.
**Please tell me how to use interactive scene correctly.** Thanks!

If you want to preview the effect, see: `https://www.bilibili.com/video/BV1R34y1W7Xn/?spm_id_from=333.337.search-card.all.click&vd_source=56f860f8bb81d49bdbd9b13dc4731f94`
At 05:04, 05:32, etc.

Look at the InteractiveScene class in manim/scene/interactive_scene.py to understand its usage. Check existing examples or tests that use InteractiveScene to see how it's instantiated and run. The goal is to write a tutorial or update the docstring that explains how to launch the interactive window and use mouse/keyboard controls correctly.
