How to update or change the email group in Emails?

We would like to change existing assets' email groups. But it looks we cannot do that on the standard menu.

We found an article that we can do it by REST API.URL: https://docs.oracle.com/en/cloud/saas/marketing/eloqua-rest-api/op-api-rest-1.0-assets-email-group-id-put.html

Is this feasible to change email groups if we use REST API?
