How Do I Customize The Live Search Results – [Astra] Review

I managed to get every element of the Astra theme exactly how I need it to look except for the live search results that dropdown from the icon/search bar in the header.

When I inspect with dev tools it shows the correct CSS code because I click the background color in dev tools, change the color and the dropdown changes color. But when I type the same code into custom CSS in customizer nothing happens. I copy & paste the exact element, change the background color but nothing happens. Is there any way to customize the results? The background is white and I need it to be grey because when you hover the text turns white and the hover color is almost white so you can’t see the text. I have literally tried every element I could find related to the live search but nothing changes at all.
