Hook to retrieve deleted domain name

Hello, I found this plugin very helpful and solved my problems regarding the license managing. The way I design the license on client side might be a bit different, in which I make client store the license data. I do this to make my server has less workload. However, every time I update the license on my server, I need to make an API call to update it on the client side too. By this reason, I can’t find a way to update the license on client side when I delete the registered domains (the domain has been deleted, so I lost the client domain). Therefore, I believe if there is a hook that allows me to retrieve the deleted domain will solve my issue.
