Background of notification

Hi,

I added a notification node to my dashboard 2. I use a dark mode theme and it is hard to see the notification. How can I change the background color of the notification?

Here is a screenshot.

I would like to use a lighter gray background to make this message easier to see.

A quick and dirty way would be to override the CSS using a ui-template

.nrdb-ui-notification .v-snackbar__wrapper {
    background-color: gainsboro;
}
