No type that describes the single-spa object that is passed to micro-frontends

[webJose]

Describe the bug or question
When working with TypeScript projects, I am currently unable to properly type the singleSpa prop because the single-spa package has no type for this object.

To Reproduce

1. Create a new Vite + Svelte + TS project.
2. Install single-spa using npm i -D single-spa.
3. Open App.svelte.
4. Declare the singleSpa property: export let singleSpa: //What does one put here? ;. Were you able to type it?

Expected behavior

I would like to be able to comfortably type the singleSpa prop using a type from the single-spa package. Something like:

<script lang="ts">
    import { type SingleSpaLib } from 'single-spa';

    export let singleSpa: SingleSpaLib;
    ...
</script>

Screenshots and/or console output

Additional context

Nothing more to add for now, but ask and I'll try to answer.

The same problem appears to exist when trying to type the mountParcel prop.
