From Patients tab, find and select the relevant patient.
In patient file, in desired care channel, click discussion thread addition icon.
At this stage, you can modify participating teams, but not individual participants.
Click Modify.
Select team to remove.
Here, the doctor team is grayed out because the message author is part of it and therefore cannot remove themselves as a participant.
It is important to understand that teams you remove from the discussion will not be notified but will still have access to the thread content in care channel.
This is what your creation page will look like if you have modified participants.
You can add message of your choice, a title, and content before sending by clicking arrow-shaped send button.
