I am on a podcast website where they have a rewind button to rewind back to 10 seconds ago. I wanted to change it to 5 second ago.

I found the onClick handler in its source code and edited the code but it didn't work and it still rewinds to 10 seconds ago not 5 seconds ago.

I am pretty sure I edited the right code but it just didn't get saved and applied to the webpage. Am I missing something here?
