Ember-simple-auth: TypeScript definitions for injected session service

[allthesignals]

I'm trying to import this service:

import EmberSimpleAuthSession from 'ember-simple-auth/addon/services/session';

So that I can use it as a type:

export default class ShowProjectController extends Controller {
  @service
  session!: EmberSimpleAuthSession

...according to the e-typescript documentation.

But TypeScript can't find the definitions. So, I was able to pull this in and have better luck:
https://github.com/Gavant/octane-bootcamp/blob/master/types/ember-simple-auth/services/session.d.ts

But, I'd hate for this file to fall out of sync to any changes across versions.

Separately, I know there's some churn on how to deal with Mixins, but we can at least type parts of the addon. Is there something I'm missing?

It's been a year on this issue. Any updates here?
