Ansible variables update via API


I am using foreman 2 with Ansible plugin.
I need to modify the Ansible variables (imported previously and with the Override check active) through the API, but I see that the Ansible variables are not considered as “Smart class parameters” (like puppet variables), so i can’t use the API to get and update/post the values the normal way:

Is there any way to do it?

Also Ansible variables don’t appear anywhere in the Host Parameters tab.

Thank you!
