Hi guys.
This PR adds support for sending Telegram notifications to specific topics in Telegram supergroups by introducing a new configuration attribute: messageThreadId.

Changes

• Added new attribute: messageThreadId
• The attribute value is used to populate the message_thread_id parameter for every Telegram message sent
• Default value is set to 0

Why

Telegram supergroups support topic-based discussions, where messages can be posted into specific topics using the message_thread_id parameter. Without this parameter, notifications cannot be routed to dedicated topics.

Backward Compatibility

• Default value 0 preserves existing behavior and supports posting to the default General topic in supergroups
• For regular groups and private chats, including message_thread_id does not break message delivery
• Existing configurations continue to work without changes

Use Case

This allows users to route notifications into dedicated topics inside Telegram supergroups (for example, separate topics for environments, services, or alert categories and our company is real case).
