如何自定义FirebaseUI-Web主题

我只想定制徽标和颜色。有谁知道解决方案吗？我只看到了安卓的解决方案。下面的代码。

 if (process.browser) {
      const firebaseui = require('firebaseui')

      console.log(firebaseui)

      const ui =
        firebaseui.auth.AuthUI.getInstance() || new firebaseui.auth.AuthUI(auth)

      const config = {
        credentialHelper: firebaseui.auth.CredentialHelper.NONE,
        signInOptions: [
          authProviders.Google,
          authProviders.Email,
          authProviders.Facebook
        ],
        signInFlow: 'popup',
        tosUrl: '/tos',
        privacyPolicyUrl: '/privacy-policy',
        callbacks: {
          signInSuccessWithAuthResult: this.signInResult
        }
      }
      ui.disableAutoSignIn()

      if (this.$store.state.userNfc) {
        this.openAppPage()
      } else {
        ui.start('#firebaseui-auth-container', config)
      }
    }
  }

我在谷歌上问了同样的问题，但什么也没找到。似乎没有兴趣以适当的方式使其成为可能：https://github.com/firebase/firebaseui-web/issues/586 https://github.com/firebase/firebaseui-web/issues/586

我尝试了 pig 老派方式在自定义 css 文件上覆盖“node_modules/firebaseui/dist/firebaseui.css”。
