How can I use 'firebase login:ci' on a build server - node.js

Question

I am running a nodejs build using Github Workflows and I want to be able to build my project and then immediately deploy it to my firebase project. Using firebase deploy. But if I want to use the firebase-tools I have to login on the build server. But there isn't a way to get authenticated via email and password etc. Is there anyway to enable me to get what I want to accomplish done? firebase-tools Inside my build script is "react-scripts build && firebase deploy"
This is my workflow file, nodejs.yml:
name: Node CI
on: [push]
jobs:
build:
runs-on: ubuntu-latest
strategy:
matrix:
node-version: [8.x, 10.x, 12.x]
steps:
- uses: actions/checkout#v1
- name: Use Node.js ${{ matrix.node-version }}
uses: actions/setup-node#v1
with:
node-version: ${{ matrix.node-version }}
- name: npm install, build, and test
run: |
npm i -g firebase-tools
firebase login
npm ci
npm run build --if-present
npm test
env:
CI: true

You don't have to use firebase login on the CI system. All you have to do is follow the instructions in the documentation to integrate with any CI system.
Use the CLI with CI systems
The Firebase CLI requires a browser to complete authentication, but
the CLI is fully compatible with CI and other headless environments.
On a machine with a browser, install the Firebase CLI.
Start the signin process by running the following command:
firebase login:ci
Visit the URL provided, then sign in using a Google account.
Print a new refresh token. The current CLI session will not be affected.
Store the output token in a secure but accessible way in your CI system.
Use this token when running firebase commands. You can use either of the following two options:
Store the token as the environment variable FIREBASE_TOKEN. Your system will automatically use the token.
Run all firebase commands with the --token flag in your CI system. The order of precedence for token loading is flag,
environment variable, desired Firebase project.
