Groups can be associated to a channel as a discussion group, to allow users to discuss about posts.

A discussion group can be associated to a channel using channels.setDiscussionGroup.
The discussion group can be accessed in the client by clicking on the discuss button of the channel, or by accessing the comment section of a specific post; the discussion group ID is also present in the linked_chat_id field of the channelFull constructor.

All messages sent to the channel will also be sent to the linked group (with sender peer from_id equal to the peer of the linked channel); those messages will also be automatically pinned in the group.
The comment section of a particular post can be disabled by removing the channel post message from the discussion group.

Linking a discussion group

To obtain a list of admined supergroups that a channel admin can possibly associate to a channel, use channels.getGroupsForDiscussion.
Returned basic group chats must be first upgraded to supergroups before they can be set as a discussion group.
Before linking a supergroup to a channel, access to the supergroup's old messages must also be enabled using channels.togglePreHistoryHidden.

To set a returned supergroup as a discussion group use channels.setDiscussionGroup.
