Regardless of your role, if you are part of an organization you do not have access to the Embedding settings of your account. Embedding is managed by organization Administrators and Owners through the Organization domain settings available on this page.
In this section Administrators and Owners can define a list of domains that can be used by any model in the organization for embedding using iframes or the viewer API.
Other users of the organization can visit this settings page to check which models are currently allowed for embedding.
Once a domain is allowed, they can enable embedding for their models in the usual way.
