Is there a way to search and auto-subscribe to WhatsApp newsletters (channels) programmatically?

[miniminiminiminiminimini]

Hi! I'm building an application that needs to discover and subscribe to WhatsApp newsletters (channels) programmatically using whatsmeow.

I'd like to implement dynamic discovery and subscription without manual intervention.

My questions:

• Does whatsmeow provide API methods to search for WhatsApp newsletters by keyword or query?
• Is there a way to subscribe to newsletters programmatically via the API, or does subscription require manual action through the WhatsApp app?
• Are there any undocumented methods or internal APIs I could use for this?

Current limitation:

• Without search/subscribe APIs, I can only work with a static, manually-maintained list of newsletter IDs. For a scalable solution, I need dynamic discovery.

I noticed WhatsApp has newsletter search functionality in the app itself — is there a way to access this through whatsmeow?

Any guidance would be helpful!
