Can the WeChat chat history backed up to mac be restored?

The WeChat chat record was backed up to the mac. After restoring it to the mobile phone, the backup on the mac was deleted. I accidentally deleted the chat record on the mobile phone the day before yesterday. Now I have used software to retrieve a lot of data on the mac. It is classified by format and has not been restored to the original folder. Now I don't know which data is the WeChat chat record backup file. What format file is the backed up WeChat chat record?
