Problem Definition

Ability to have a button to update the technical contact in the Admin portal under "Billing details" section as we currently have it for Billing contact.

Suggested resolution

To add a billing or technical contact, any existing billing or technical contact can log into my.atlassian.com, select the product or subscription in question, and enter the email address of the new contact. Once you add the new contact to establish this contact as a new primary billing or technical contact, the new contact will need to log into my.atlassian.com and select Make Primary. The existing primary contact will then be demoted to a secondary contact and can be removed if needed.
