Kotlin/Js add npm dependency from custom registry - kotlin

Question

I'm developing an application with Kotlin/JS and Gradle. I can easily add npm dependencies from the default npm registry with the implementation npm("query-string", "7.0.0") command.
However, I cannot add an npm dependency from a different npm registry like Github Packages.
I want to add this npm dependency to my project. Without gradle I could just install the dependency by just using the command line and npm install #gitliveapp/firebase-firestore but this doesn't work with the gradle npm command. I also tried implementation npm("#gitliveapp/firebase-firestore", "0.5.4") but this produces the following error: Couldn't find package "#gitliveapp/firebase-firestore#0.5.4" required by "project" on the "npm" registry..
How can I add npm dependencies with gradle from different registries other than the npm public registry.

Unfortunately, you can't do it via gradle now, see an issue.
But you can create file .npmrc (or .yarnrc) in the project root and configure here (https://docs.npmjs.com/configuring-npm/npmrc.html)
Additionally see the documentation:
For example, to use a custom registry for npm packages, add the following line to a file called .yarnrc in the project root: registry "http://my.registry/api/npm/"
