namespace app is not defined for enums from external types package

I am generating my Typescript types through my Laravel project with Spatie Typescript Transformers. I am then importing the Types & Enums into my Nuxt project through a separate package via node modules

It looks like this

// node_modules/@laravel-types/index.d.ts

declare namespace App.Enums {
    export enum ExampleEnum {
        "ExampleValue" = 0,
    }
}
declare namespace App.Models {
    export type ExampleType = {
        id: number;
        title: string;
        enum: App.Enums.ExampleEnum;
    };
}

I have no problem using the types of App.Models throughout my Nuxt project. But when using the App.Enums I am getting the error Uncaught (in promise) ReferenceError: App is not defined

I have tried to change my nuxt.config.ts compiler options adding declaration & declarationMap and include the package

// nuxt.config.ts

  typescript: {
    shim: false,
    strict: true,
    typeCheck: true,
    tsConfig: {
      compilerOptions: {
        declarationMap: true,
        declaration: true,
      },
      include: [
        '../node_modules/@larave-types/types/index.d.ts',
      ],
    },
  },

But that doesnt work. Seemingly the enums shouldnt be declared in a d.ts file. But since thats an external package I have no influence over the content inside it. So I need to find a way to deal with it as it is

I have also tried to add the enums as local ts file which are referencing the type of the enums from the package like

//./types/enums.ts
export const ExampleEnum: typeof App.Enums.ExampleEnum = {
  ExampleValue: 0,
}

this works locally but then the gitlab.ci pipeline is throwing me an error

types/enums.ts(1,42): error TS2708: Cannot use namespace 'App' as a value.
