Re-add the office 365 owners inside the sharepoint site collection admin

Question

I have create a new Private sharepoint team site named TestUserPer1, where by default i will get this group added as site collection admin:-

Now i mistakenly remove the above group from the site collection admin, so i tried to re-add it again, but the auto-complete did not return any entity named "TestUserPer1 Owners" ... any advice (i only get "TestUserPer1 Members")?

Thanks

By default, you cannot add Microsoft 365 owners group into site collection administrators.

Go to SharePoint admin center -> Active sites -> Select the site -> Permissions -> Click "Add the group owners as primary admins" -> Then Microsoft 365 group owners group will return to site collection administrators.
