How can I edit the CSS of the Tyche theme?

How can I edit the CSS of the Tyche theme, could anyone help me? I can not find the codes in the style.css file.

Hello there,

I hope you are doing well today.

In order to change the CSS, you need to go to Appearance > Customize > Additional CSS and add any new CSS there. If you add CSS to the style.css file, the changes can be deleted if the theme is updated.

Best Regards,
