i am using React select component for my dropdown selections. All functionality is working fine but i am unable to style the selected option background color when the option is selected from the dropdown. Tried few options but that too not working.

Below is the code for the same :-

import React, { useContext, useState } from "react";
import moment from "moment";
import Select from "react-select";
import DataProvider from "context/DataContext";

export default function Compare() {
  const [selectedValue, setSelectedValue] = useState([]);
  const {
    fromDate,
    toDate,    
  } = useContext(DataProvider);

  const customStyles = {           
    option: (base, state) => ({
      ...base,      
      color: "#1e2022",
      backgroundColor: state.isSelected ? "rgba(189,197,209,.3)" : "white",
      padding: ".5rem 3rem .5rem .5rem",
      cursor: "pointer",
    }),       
    singleValue: (provided, state) => {
      const opacity = state.isDisabled ? 0.5 : 1;
      const transition = "opacity 300ms";

      return { ...provided, opacity, transition };
    },
  };

  const options = [
    {
      value: [
        moment(fromDate).subtract(1, "days"),
        moment(toDate).subtract(1, "days"),
      ],
      label: "Previous Day",
    },
    {
      value: [
        moment(fromDate).subtract(7, "days"),
        moment(toDate).subtract(7, "days"),
      ],
      label: "Previous Week",
    },
  ];

  const handleApply = (event) => {
    setSelectedValue(event);
  };

  return (
    <Select
      onChange={handleApply}
      options={options}
      styles={customStyles}
      placeholder="Compare to Past"
    />
  );
}
