Envato wordpress toolkit

Hello, I have a multisite wordpress installation. I have buy a theme and installed the Envato Wordpress Toolkit.
In the Multisite dashboard I have inserted my username and API in the Envato Wordpress Toolkit and in the main site the popup:

To enable *** update notifications, please enter your Envato Marketplace credentials in the Envato WordPress Toolkit Plugin

disappear but not in the other sites.

How can I remove the advice from the other sites?

Thank you
