Need to import Avada license into client's Envato account

My client’s site was set up by another developer who purchased Avada for them in her own account. I have the license number and have registered that number on the site, but I still need to move the license into my client’s Envato account so I can access updates to the theme. My site says the Avada version is current but it is 6.1.2. and I don’t see anywhere to turn on auto updates.

I’m not even sure how to check and see if she still has it in her own account.

I’d love some assistance here. Thank you!

This type of transfer is not allowed. Item update download and support only for the purchaser account.

Thanks
