To copy your request headers follow the instructions from the [ytmusicapi docs](https://ytmusicapi.readthedocs.io/en/stable/setup/browser.html) under "Copy authentication headers".

 If you're running the command line (CLI) version of YTMusic Deleter, press `Enter` after pasting the headers, then press Ctrl-D to continue (Ctrl-Z then Enter again on Windows). The next time you run ytmusic-deleter, it will reuse your headers from the `headers_auth.json` file that it generated. If you're running on macOS, you should create the `headers_auth.json` file manually, as the MacOS terminal application can only accept 1024 characters pasted to std input.
