[Question] Calling configureTnsOAuth after app bootstrapping

In my Nativescript-Vue app, I need to configure a Microsoft provider with data received from a web request. Since it's not recommended performing asynchronous tasks while the app bootstraps, I make my request when the first page loads and then I configure the provider through configureTnsOAuth. While this works well on Android, on iOS something strange happens. After a successful login inside the webview, redirect doesn't work and I can't go back to the app unless I cancel.

I am aware that the documentation tells to configure the providers on startup, but is there a way to do it inside a component?

EDIT:

I implemented this and now it works, is it safe or might it cause issues?

main.js

import * as platform from "tns-core-modules/platform";
import { TnsOAuthClientAppDelegate } from "nativescript-oauth2/delegate";

if (platform.isIOS) {
  application.ios.delegate = TnsOAuthClientAppDelegate;
}

FirstPage.vue

// ...
async onPageLoaded() {
  let config = await api.getAzureConfig();

  let provider = new TnsOaProviderMicrosoft({
    openIdSupport: "oid-full",
    clientId: config.clientId,
    redirectUri: "myscheme://mobile-auth/",
    urlScheme: "myscheme",
    scopes: ["openid","email","profile","offline_access"]
  });
  provider.authority = config.authority;

  configureTnsOAuth([ provider ]);
}

// later on
login() {
  return new Promise((resolve, reject) => {
    let client = new TnsOAuthClient("microsoft");
    client.loginWithCompletion((tokenResult, error) => {
      if (error) reject();
      else resolve(tokenResult);
    });
  });
}
// ...
