Access to the default service ID in the Services tab in the user profile in the admin area

[marya]

Hello,

I have a scenario where I am viewing a user's profile in the admin area and navigating to the Services tab. The issue is that the default selected service ID does not appear in the query string as "productselect", so it cannot be accessed via the GET method.

How can I retrieve the ID of the default active service selected in the Services tab if it's not available in the query string?

Is there any other way or hook that allows me to access the ID of the selected default service?

Thank you.
