Open upload application menu on your dashboard.

Google cloud platform console

Here you will find the direct link to your environment specific GCP storage bucket. Only accounts added as users to the application environment have access to the bucket.

The link always contains your application environment id which you can find on the General Info page.

{appEnvId}: Your application environment id.

Once your upload is finished you can go to the Version Control page, where you can create a new version for your application.

After creation is finished and the new version usable, you can then activate it to deploy it.
