Remove bullet points in footer menus

Hi,

I have created a footer menus and I am trying to get rid off bullet points created under the menus.

How do I get rid of them?

I have googled and tried to update this piece of code in the theme customize? additional CSS

/* hide bullets in the footer menus*/

.no-list-style ul {
list-style-type: none;
}

Unfortunately, I am not able to get rid of them.

Also I tried custom css plugin and implemented the same code.Still didn’t work.

Am I missing something? Any help is appreciated much.
