What article on docs.github.com is affected?

This one about creating a team doesn't state the allowed syntax for a team name: https://docs.github.com/en/organizations/organizing-members-into-teams/creating-a-team
And this page on CODEOWNERS, https://docs.github.com/en/repositories/managing-your-repositorys-settings-and-features/customizing-your-repository/about-code-owners#codeowners-syntax, doesn't mention it either.

What part(s) of the article would you like to see updated?

A section on syntax for team names should be added.

A team name with '.' included is not allowed in a CODEOWNERS file, resulting in the following error:

and the error description points to the characters from the dot to the end.

I would assume that casing of the team name is also critical. There might also be other non-allowed characters besides those mentioned on the CODEOWNERs page.

Additional information

This would affect all organizations that are using team names with dots.

This syntax is correct:
