I would like to know how I can set someone else as the super admin of a Zoho Account?

I was asked to test Zoho Assist and after 15 days the trial was over. I was the only one who was considered an administrator that could make a payment. So we did with my account, but in fact it should be someone else.

How can I switch the Super Admin feature for finances, etc. bu passed to someone else?

Thank you very much for you help,
