Transfer product from different owener

Hello,
the client asked me to take over management of the site built on WordPress plugins and themes purchased on Themeforest. Can I somehow transfer purchased a license package for the client to have access to updates?

The original site admin gave me an activation code.

Thank you for answer.

The updates will only ever be from the purchase account.

Transferring the license permits the singular use of the file but access to downloads is restricted to prevent exploitation.

Thanks for your reply.

Did i undestood correctly: There is no way how to transfer updates to another account?

You can transfer the license to use the file but not access to downloads of updates etc.
