Find/Search > Go to Chat. should take you to that point in time during the chat. Not just the chat window.
I want to search for a conversation within a full chat with someone. So, I use keywords in the search function. Teams will find the single message in which I used that keyword but single messages are out of context.
The Go to Chat feature just takes you to that chat at the latest message. It should take you to that specific point in time in the chat so that you can see the full context of the conversation.
Trying to scroll through days of endless chatter is cumbersome.
