如何设置react-bootstrap的导航栏组件的图标栏样式？

import React from 'react';
import { Navbar, Nav, Icon } from 'react-bootstrap';

const NavigationBar = () => {
  return (
    <Navbar bg="light" expand="lg">
      <Navbar.Brand href="#home">My Website</Navbar.Brand>
      <Navbar.Toggle aria-controls="basic-navbar-nav" />
      <Navbar.Collapse id="basic-navbar-nav">
        <Nav className="mr-auto">
          <Nav.Link href="#home">
            <Icon icon="home" /> Home
          </Nav.Link>
          <Nav.Link href="#about">
            <Icon icon="info-circle" /> About
          </Nav.Link>
          <Nav.Link href="#contact">
            <Icon icon="envelope" /> Contact
          </Nav.Link>
        </Nav>
      </Navbar.Collapse>
    </Navbar>
  );
};

export default NavigationBar;
