You have a couple of options here:

1. In the src dir for newly created applications there is a file typings.d.ts which you can use reference your team member's .d.ts file which will expose those types throughout your application.

2. In the tsconfig.json file you can add the path to the node_modules folder where this package lives to the typeRoots array which will make those typing available too.
