Publish a content type
You can publish, unpublish, or republish content types in the content type hub at /sites/ContentTypeHub or from the SharePoint admin center.
To publish, republish, or unpublish a content type
Go to the Content type gallery in the SharePoint admin center, and sign in with an account that has admin permissions for your organization. The Content type gallery page isn't available if you have the global reader role.
Under the Site content type column, select the name of the site content type for which you want to manage updates. That site content type page appears.
In the menu bar, select Publish. The Manage Publishing panel appears.
On the Manage Publishing page, do one of the following:
To make this content type available for download to all sites in the organization, select Publish.
To publish updates to this content type, select Republish.
To make this content type unavailable for download to sites in the organization, select Unpublish. Any copies of this content type being used in other sites will be converted to a local content type.
