Stop opening last chat when launching

Recently on iOS the UI switched to a tabbed system, which is cool and all, but at the same time the app lost the ability to back out of all chats such that I don't get dumped into whatever the last chat I touched was when launching the app. I used to be able to do this by going to the online friends list, but now the app is frustratingly sticky about going back to the last touched chat.

Current:

1. Chat with someone
2. Be done chatting with them
3. Try to find some way to get Discord not to dump me back into the chat the next time I launch it
4. Fail miserably
5. End up dumped back in that chat next time I launch Discord.

Desired:

1. Chat with someone
2. Be done chatting with them
3. Back out of the chat (NOT DELETE OR ARCHIVE OR WHATEVER, just leave the chat where it was all tucked safely away for later)
4. Launch Discord later to chat with someone else, and be pleased to not be shoved back into whatever the last chat I touched was.

It's very distressing to me not to be able to reset the app to a quiescent state when I feel like I'm done chatting with someone for the moment. Worst case scenario I'll be like 'oh hey RL friend, let me show you a hilarious meme someone else sent me on discord' and I open the app and it's a wall of private pics from some chat I forgot I was having like 6 hours ago.
