"show clipping" not working?

[s30584u25C9C]

So I'm following this adobe tutorial: https://helpx.adobe.com/photoshop/using/levels-adjustment.html and it says that I should be able to see areas that are being clipped by holding Alt and dragging the black and white sliders in the levels menu, but nothing happens when I do so. I've also looked up tutorials and some people do the same thing but using the curves tool, however that doesn't work for me too. My photoshop also doesn't allow me to choose Show Clipping from the curves panel menu (picture). Am I doing something wrong?
Sorry if my english isn't entirely understandable.

What version of photoshop and operating system are you using?

Windows, version 23.1 I believe

Hi

Are you Alt+Dragging these sliders or the Output sliders underneath?

Hello, I've actually tried dragging all of them... When I drag those that you've pointed out (while pressing alt of course) it just makes my whole picture lighter or darker. From what I know, when I'm dragging the black slider it should slowly reveal the darker areas of my picture which should look like this:

You asked about the Levels adjustment layer (my screenshot), and your link points to Adobe Help on Levels.

Your screenshot is the Curves adjustment layer. Here is help for Curves:

Yes, as it's written in my post, I'd seen people that make photoshop tutorials use this technique in the curves menu too, so the screenshot comes from one of those tutorials because it is the only way I could show you what I understand should happen after dragging the sliders. I assumed the same thing appears when you press alt and drag the sliders in the levels menu.
I have tried dragging the sliders in the levels menu as you showed on the picture above.

I have just noticed your edit. I will try that tutorial too, thank you.

If, for example, you make a Levels Adjustment Layer, go to the properties panel flyout menu and click Show Clipping for Black\White Points, then does moving either the Black Point or White Point slider do anything?

This worked, thank you very much!

Did you try the alt key on both sides of the keyboard?

It wouldn't hurt to reset the photoshop preferences if the above doesn't make any difference.

In photoshop go to Edit>Preferences>General, click on Reset Preferences on Quit and restart photoshop.
