Cannot "Unhide" multiple chats from search results
Once a Chat is hidden, the only way to get it back is to search and then once selected you can "unhide" it. The problem is if that was not the one you wanted, you have to search again, find the one you wanted go through the process again.
You should be able to select multiple chats from the search results so they all show up in your private chats and then you could unhide them all.
Chats should have a "hide" / "unhide" icon directly in the private chat display so you do not need to go into the ellipsis (...) to hide/unhide chats.
In the Chat Window itself, there should be a "Hide" button.
Scenario: You are having a private (or group) chat. The Chat is "over" and there is no reason to keep it in your "Recents" since the topic was transient/time sensitive only. You should be able to "Hide" (Close) the chat right from the Chat window. Do not make the user click multiple times to get back to "Recents", then find the Chat, click again to get the option to Hide and then have to click "Hide".
Unnecessary clicks reduce productivity, reduction in productivity is an increase in expense which reduces overall company profits.
