To use Backup WA Chats, users need to open the WhatsApp web version and select the chat they want to download. Then, they can choose the backup option and click the "Start" button to initiate the backup process. The extension also attempts to download chat media if it still exists on the user's phone.

Users can specify a time period for the backup using the Dates fields. If the Download button doesn't work, users can try reloading the page and trying again. However, it's important to note that due to a recent update in WhatsApp, users can now only export 90 days of chat history. To download complete chats, users may consider downgrading to an older version of WhatsApp.

It's worth mentioning that Backup WA Chats is not affiliated with or endorsed by WhatsApp, LLC. Users can contact for any questions or support related to the program.
