Unable to set up Okta with Vue3 using Composition API

Questions
1

I’m trying to get Okta to work using Ionic and Vue 3 composition API.

In main.ts

import { OktaAuth } from '@okta/okta-auth-js';
import OktaVue from '@okta/okta-vue';
import oktaConfig from '@/oktaConfig';

const oktaAuth = new OktaAuth(oktaConfig.oidc)

const app = createApp(App)
  .use(IonicVue)
  .use(router)
  .use(OktaVue, { oktaAuth });

And in App.vue the sidebar menu will have a login button.

<ion-button v-else @click="login">Login</ion-button>

 setup() {
    const login = async () =>{
    await OktaAuth.signInWithRedirect({ originalUri: "/" });
    }
}

I’m struggling with figuring out how to import okta here to get the “signInWithRedirect” to work.
