Is your feature request related to a problem? Please describe.
The package currently does not allow sending messages to a Substack newsletter chat, which prevents interacting with subscribers through this channel from the Substack App or via automation workflows.
Describe the solution you'd like
Add support for sending messages to a Substack newsletter chat from the Substack App.
Describe alternatives you've considered
Manual posting through the official Substack app, or using posts/emails instead of chat messages, but these do not cover the same use case.
Additional context
This feature would enable automation and integrations that communicate directly with subscribers via the newsletter chat. If the API does not support this, documenting that limitation would also be helpful.
