I have made a search on google but i didn't found a results. Is there an extension that track user's actions, so we can know which user create an invoice
Check this free extension: https://github.com/kiwicommerce/magento2-admin-activity It's recommended to install via composer for it to work correctly.
You'll need to enable the extension and turn on modules as you need (e.g Order) in configuration, after that, you can see the action by going to
System > Admin Activity by KiwiCommerce > Admin Activity.
I tested with creating invoice and it is able to do what you need. (magento ce 2.3)
