Hover color for sticky nav with transparency

Hello, I used custom CSS to adjust the color of the sticky nav to be 0.7 transparency. I noticed than when hovering over a link it still shows the solid color box around the selection. I would like to add some code to make the background of the hovered item look transparent so only the color of the text changes.

Here is the code I added to create the transparency of the sticky menu:

.main-navigation.navigation-stick {
background-color: rgba(31, 38, 65, 0.70);
}

I'm curious what I should add to make the box around the hovered item look the same?

Thanks for your help!
