What's Wrong?

On the Claude Code Desktop app via the Teams plan,
I am unable to rewind my first message of the conversation.

In case I have made some mistakes in the opening message of the conversation itself.

I have no option but to delete the chat and start it again.

What Should Happen?

Like Claude Code CLI, it should let me reword my first message too.
