iPhone "mirroring" Mac Enter key not sending messages, adds new line instead

I’m using iPhone mirroring on my Mac, and I’ve noticed that pressing the Enter (Return) key in any chat app doesn’t send the message as expected. Instead, it just moves to the next line, and I have to manually click the send button every time, which is really annoying. This happens across all messaging apps, including instagram, WhatsApp, etc. I’ve tried different keyboard shortcuts like Command + Enter, but nothing seems to work. I’ve also checked my keyboard settings on both my Mac and iPhone, but I can’t find a solution. Has anyone else experienced this issue? If so, did you find a fix?
