Build fails after updating to Angular 20/ new builder

[DisplayName522]

Hi, thanks for the library!
After updating to Angular 20 and the new build system ("builder": "@angular/build:application" instead of @angular-devkit/build-angular:browser) I got the following error:

X [ERROR] TS2307: Cannot find module './lib/generate' or its corresponding type declarations. [plugin angular-compiler]

Found a workaround:
Create a file typings.d.ts with the following content:
declare module 'ibantools-germany/esm/*'; declare module 'ibantools-germany/cjs/*';
