How to pass environment variables to a reusable workflow in Github Actions

In the GitHub actions console I have an environment created for my workflow. This environment has certain variables like account_number etc. I want to pass this value into the resuable workflow.

name: Deploying Lambda

on:
  pull_request:
    types: [closed]
    branches:
      - 'dev'

jobs:

 unit-tests-execution:
 # job details here

 my-job:
   needs: unit-tests-execution
   uses: myorg/myrepo/.github/workflows/[email protected]
   with:
     ACCOUNT: <assign the variable account_number from the DEV environment here>

How to assign the variable account_number saved in the DEV environment created in the Github console to the reusable workflow input variable ACCOUNT?

If I do this below I get an error saying environment: can't be used with uses:

 my-job:
   needs: unit-tests-execution
   environment: DEV
   uses: myorg/myrepo/.github/workflows/[email protected]
   with:
     ACCOUNT: ${{ vars.account_number}}

I don't want to set the environment in the reusable.yml workflow because that workflow will be used for different accounts and should have just the account number passed in.

Variables don't propagate into the called workflows, but you can use workflow inputs and pass the values in using with.

I have created and tested this minimal example illustrating the technique:

.github/workflows/reusable.yml:

name: Worflow with input
on:
  workflow_call:
    inputs:
      my-arg:
        required: true
        type: string

jobs:
  print_input:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - name: display my arg
        run: echo ${{ inputs.my-arg }}

.github/workflows/reuser.yml:

name: reuser
on:
  - push
jobs:
  reuser:
    uses: ./.github/workflows/reusable.yml
    with:
      my-arg: top level reuser
