How Do I Add Line Numbers to a Code Block?

Hi! I’m using the Highlighting Code Block plugin, and while it works great for adding syntax highlighting, I can’t figure out how to add line numbers to my code blocks. I’m using the Block Editor, and I don’t see any option in the settings for enabling them.

Do I need to add custom CSS or adjust the plugin’s configuration somewhere? If there’s a specific way to enable this feature, can you explain how to do it step by step?

Thanks for the help!
