Are repoServer ENVs usable for Sidecar Plugins?

[Moep90]

Good Morning from Germany,
I'm currently migrating from argocd 2.4 to 2.6.
I'm using a sidecar plugin and would like to pass an existing env variable from the repoServer into the sidecar plugin execution.

apiVersion: argoproj.io/v1alpha1
kind: Application
[....]
    plugin:
      name: kapitan-v1.0
      parameters:
[....]
        - name: VAULT_TOKEN
          string: ${my_VAULT_TOKEN}

When passing the VAULT_TOKEN as string here, this works. referencing an ENV seams to not work.
Does anyone has a tipp on how I can achieve that?
Another option I see is to pass the envs directly into the plugin extraContainer, but it does not seem to have this option atm.

Cheers guys!
