This article explains how to send a post to topics.
How it works
Telegram topics are themed subgroups in forums. The feature lets you create separate chats inside the main group for particular discussions. Members can chat using the full set of familiar tools, including polls, pinned messages and bots.
Once topics are added, the group effectively turns into a list of discussion topics that members can join.
If you open the main group link, the list of topics opens.
