You can manage many conversation actions using the conversation menu. Open the conversation and tap . From this menu, you can:
Members: to see a list of all members of the conversation.
Mark All Read: marks all posts in the conversation as read.
Mute: muting a conversation hides it from your list of conversations and stops messages about it from appearing in your email digest if you chose to have one sent to you.
Change the conversation name.
Show or hide membership messages. These types of messages show when a person was added to a conversation and who added them.
Close or Open: change the status from open to closed. Closing a conversation prevents people from adding new messages to it and removes it from people's list of conversations.
Discard: delete the conversation. This option only appears if you created the conversation.
Share Link: send a link to the conversation using an app on your device. When you tap this option, a list of apps appears that you can use to send the link.
If the conversation was created about a file, you can also use the Go to Document option to open the file and view it. If the conversation was started about a folder, there’s also a Go to Folder option.
