Automatic accounts deletion

Hi!

For GDPR purposes, I would like to automatically delete all accounts when users have not logged in for more than 3 years (maybe less). Is there a way to achieve this within the armember plugin? Or do I have to create a cron?

In this case, in which tables should I delete data? And I also have to update WordPress and Mailster users tables as they are synchronized with Armember. This seems to me very complicated.

If anyone has already been in the same situation, any idea is welcome!

Thanks in advance for your help.
