The error 'Facebook page already in use' occurs when your Facebook page is linked to another Zendesk subdomain or trial account. This means that the page has been previously associated and needs to be removed from the old account before it can be added to a new one.
To resolve this, if you still have access to the old subdomain, you should remove the Facebook page from there and then try adding it again. If you no longer have access to the previous account, you will need to contact Zendesk Support. Use the widget at the bottom of the help page and provide them with your Facebook business page link, the old subdomain, and the new subdomain. For more details, you can refer to the article onAdding Facebook Messenger channels to the Zendesk Agent Workspace.
