There is no information about a group topics. I tried to find any information on the official site.

Functions client.iter_dialogs() and client.get_dialogs() don't consider topics. They return only lists of opened conversations.

When I tried to send message to group with a topic using function client.send_message(), I get errors when topic "General" was closed.

When it was open, I didn't get any errors, and a message was sent to the "General" topic of the group. I understood that function send_message() can send message to group with topics. So, I want have posability to choose a topic and write there. And get list of topics where user already wrote any messages, from opened group dialogs.

I sent a few messages by Telegram and got its log. Found the part where it sends the message. I didn't understand where it sends topic ID. TL_messages_sendMessage didn't get any parameter. And "send message" either.

Log below:
