Do you have the sound effect for when your clock turns red?

To get any sound file:
1. Choose the Sound Theme you want in settings.
2. Open a page with a game. An easy way to do this is just start a game with a bot.
3. Open DevTools by either pressing F12 or right-clicking and selecting "Inspect."
4. At the top select the "Network" tab. Make sure "All" or "Fetch/XHR" is selected in the container under the tabs.
5. Hit ctrl+r or reload the page and trigger a sound event in the game (e.g. make a move)
6. Find the files that end with ".webm." They should be at the very bottom of the "Network" tab.
7. Double-click the sound you want.
I'm looking for chessboard sound effect files (vaw or mp3 format) at a normal move, at a capture move or at a check move...
Where can I find it?..
Thanks,
