#1744-Sidebar Option Not Included in CSS Customization Settings

Hello team, While working on customizing the appearance using CSS, I noticed that the specific option in the sidebar "Settings" is not included or does not reflect any changes through the CSS customization panel. Please check if this option can be added to the customizable elements, or advise if there's an alternative method to target it via custom CSS. Thank you for your continued efforts and the great work you’re doing.
