How to active lsp for some part of a file (cssls for styled component

how to active cssls inside ` … ` part of js or ts or tsx or jsx file.

for example:

import styled from "styled-components";
import { Color } from "styles";
import { Div } from "..";

export const LayoutFooterContainer = styled(Div)`
  width: 100%;
  height: 2.5rem;
  margin-top: auto;
  line-height: 2.5rem;
  display: flex;
  align-item: center;
  background: ${Color.BackgroundSecondary};

I want to enable cssls inside styled component area, after



  background: ${Color.BackgroundSecondary};

cssls work outside of backtick but inside of backtick is not working at all.
