API Question befor buying PRO version

Hi, we are considering buying the PRO version because we have many missing entries.

I don’t understand this step in the documentation for getting the API activated tu use manual method in the plugin.

11. After getting startedselect the user type and click on the “Create” button.

With GSheetConnector as it requires authentication if you are selecting an Internal user type then you will require the same organizational domain email Id.

Example: If you create an API within an organization i.e gsheetconnector.com then while authentication the user email id must be of the same organization i.e [email protected]

And if you are using an External user type, you would need to verify our app by creating and providing a link to a YouTube video that shows how you will use the data you access using OAuth scopes. This will be a process of 5-6 days if you provide a quick response.

I don’t understand what this means “you will require the same organizational domain email Id”.
Could you please clarify this point?
We need the missing entries issue solved asap so we want to understand how to properly set the configuration and the API request.

Thanks in advance.
Kind regards.
