Realm Functions importing dependencies: Cannot find module ‘firebase-admin/app’

I have been attempting to use the firebase-admin sdk as an external dependency within a Realm app service. Have tried adding the module through directly through the UI, as well as a file (which appeared to nearly exceeded the size limit for uploading such a file), and lastly performed the steps to add dependencies through the CLI, but even after confirming that firebase-admin was successfully pushed to the Realm app as a dependency, I encountered the module not found error when running from the UI. Despite this, the @google-cloud/storage sdk was added as a dependency (both from UI and CLI) and was able to be import and use it without any issues at runtime.

Is it possible that the size of the package is too large and it is not being attached to the runtime?
Any ideas on what might be causing the issue are appreciated.
