Hi @skchauhan
Navigate to Settings > Secrets > Actions
Add your environment variables (secrets) with their corresponding values
These secrets can be accessed in your GitHub Actions workflows

in your .github/workflows directory, create or modify a workflow YAML file (e.g., main.yml)
use the environment variables (secrets) in your workflow steps.
in your JavaScript files (such as in the blocks folder), you can access the environment variables using process.env.VARIABLE_NAME
