Describe the issue

I'm encountering a dependency conflict when trying to install the @auth/firebase-adapter package alongside firebase-admin@12.4.0. The @auth/firebase-adapter package requires firebase-admin@^11.4.1, which is incompatible with the installed version (12.4.0). This results in an ERESOLVE error, making it impossible to resolve the dependency tree.

Operating System :- Windows 11
node Version :- 20.12.2

How to reproduce

Expected Behavior:
The @auth/firebase-adapter package should be compatible with the latest version of firebase-admin (v12.x.x) or provide guidance on how to resolve the conflict.

Actual Behavior:
The installation fails with the following error:

Start by reproducing the conflict with npm install @auth/firebase-adapter alongside firebase-admin@12.4.0 in the linked reproduction. Inspect the @auth/firebase-adapter package metadata and its firebase-admin peer dependency, then verify installation with the supported versions. Done means the dependency tree resolves for the intended Firebase Admin version or the package documents a confirmed workaround.
