Do we need different credential for creating runner and access GCS

I have the following GitHub action file,
```sh
jobs:
deploy-runner:
runs-on: ubuntu-20.04
steps:
- uses: iterative/setup-cml@v1
- uses: actions/checkout@v2
- name: Deploy runner on GCP
env:
REPO_TOKEN: ${{ secrets.REPO_ACCESS_TOKEN }}
GOOGLE_APPLICATION_CREDENTIALS_DATA: ${{ secrets.GOOGLE_APPLICATION_CREDENTIALS_DATA }}
run: |
cml runner \
--cloud=gcp \
--cloud-region=us-central1-a \
--cloud-type=n1-highmem-2 \
--labels=gpu_runner \
--single=true \
--cloud-gpu=nvidia-tesla-t4 \
--cloud-spot=false \
--cloud-hdd-size=128

training:
name: Training and Reporting
needs:
- deploy-runner
runs-on: [self-hosted, gpu_runner]
steps:
- uses: actions/checkout@v2
- uses: iterative/setup-cml@v1
- uses: iterative/setup-dvc@v1
- uses: actions/setup-python@v2
with:
python-version: '3.10'
- name: Training
env:
repo_token: ${{ secrets.REPO_ACCESS_TOKEN }}
GOOGLE_APPLICATION_CREDENTIALS_DATA: ${{ secrets.GOOGLE_APPLICATION_CREDENTIALS_DATA }}
run: |
# Pull dataset with DVC
dvc pull data

# Reproduce pipeline if any changes detected in dependencies
dvc repro
```
The `deploy-runner:` job working without any issue but `training` job fail in `dvc pull data` and it's give the following error
```sh

According to the documentation [cloud-storage-provider-credentials]( https://cml.dev/doc/cml-with-dvc?tab=Google-Cloud-Storage#cloud-storage-provider-credentials) the `GCS` environment variable is `GOOGLE_APPLICATION_CREDENTIALS` but i'm using `GOOGLE_APPLICATION_CREDENTIALS_DATA` is this the issue or i'm missing something

Thanks
