Transfer WeChat history from Mac to iPhone (not the other way around)

My phone broke and was forced to get a new phone without backing up my WeChat chat history. However, because I always use the MacOS app, I still have my entire history on my Mac. But I can't seem to find a way to transfer that history from my Mac to my new iPhone, only the reverse. Is there a way to create a backup from my the data on my Mac instead of from the data on my phone?
