How to use "firebase-tools" in own functions?

[motschel123]

I tried to implement my own custom version of delete-user-data but I cannot manage to import firebase-tools to make use of it's recursive delete function.
I used "npm install -g firebase-tools && npm install firebase-tools" to get the needed node_module into my project but at import it says "Could not find a declaration file for module 'firebase-tools'.".
I tried npm i --save-dev @types/firebase-tools but it doesn't find any types and I couldn't find declaration file for firebase.tools.

In your delete-user-data extension you manage to import and use firebase-tools, can you describe how you did it?
