1. Go to any chat
2. Open thread menu
3. Open `Create new subchannel`
4. Try to create any subchannel via `ComposeSubchannel`
For now, we don't have implemented announcement channels yet. In this case, when we try to create any type of announcement channels, this communiqué will appear:
{F178017}
In other cases, after successfully thread creation, we will be redirected to a newly created subchannel.
