EmberJS single page application with Okta sign-in widget

I wonder if someone could guide me on how to integrate the Okta auth widget into an EmberJS single page application. There is no EmberJS SDK anywhere in the Okta docs. The add-on ember-simple-auth-okta currently only supports local storage. I’m new to EmberJS, tasked with maintaining an Ember v3.4 app, and integrate it with Okta SSO, lucky me. Appreciate any assistance.
