Add conversation members
Go to the conversation details and hover your mouse over recipients, which is located in the upper
right of the screen and click on the Add members button.
A modal window pops up with the conversation name at the top, so you can double check you
haven't mistakenly clicked on a different conversation.
Now you can start typing your colleagues’ names and our autocomplete feature will speed up the
process for you. Click the Add members button and that's it!
Note that people that are already members of the conversation won't be shown in the
"select users" input.
