Hey @pavelzw,

Thank you for opening this pull request!

I believe a better approach to achieve your goal is to export the OIDC token as an environment variable, which can then be utilized throughout the rest of your workflow.

Make sure to use clear and descriptive names for the variables and ensure they are cleared during the post-action phase to avoid any security risks.
