Need Help : SendGrid unsubscribe group

Hello, I would like to know how to manage the SendGrid unsubscribe group thorough Bubble and SendGeid plugin (Copilot).
My app will send e-mail newsletters to users. My app also has an function to send URL for document download. In case some user unsubscribe our email newsletter, I think the user cannot receive emails for document download either.
Is it possible to stop only email newsletter (not download URL)?

Best regards,
