Sysmanagement_shared_registered_servers *Tables*

I have 240 sql server instances to enter into CMS and I would like to insert them via TSQ.
sysmanagement_shared_registered_servers is a view but I cannot find the underlying tables to insert into. This is SQL 2022
Any ideas? Thanks.

Thanks, Ifor. Sorry for the duplicate posts.

[msdb].[dbo].[sysmanagement_shared_registered_servers_internal] is the table name I was trying to think of.
