E.g. /todo Set up meeting for convention
You will be prompted to select the other participant of this conversation
In this example, it is Blake
The reason why we ask you to choose the other participant is because Slack views this conversation as private and does not provide our app with the information as to who is in the conversation.
We need to confirm who is in the channel to create the list correctly.
Choose the correct person in the channel.
You will be asked to confirm your choice. Press OKAY
The task will be created in the direct message with Blake and be shown in the Slack channel
You have now created a list in a direct message
