-> [!NOTE]
->
-> `publish-extension` does not load any `.env` files, you're responsible for making sure the environment varaibles are set while running the command. In CI, this is easy, but to run the command locally, you'll need to use something like the `env-cmd` package:
->
-> ```sh
-> pnpm env-cmd -f .env.submit publish-extension ...
-> ```
+`publish-extesion` will automatically look for a `.env.submit` file and load it if it exists.
