THEME matchType missing in Report V3 documentation

[IgniteMosquito]

There is no update to the matchType documentation about THEME.
We do not know where it is available if it's in SearchTerms, or just the Targeting report.

Example of missing documentation:
https://advertising.amazon.com/API/docs/en-us/guides/reporting/v3/columns#matchtype

Another, for SB Targeting report:
https://advertising.amazon.com/API/docs/en-us/guides/reporting/v3/report-types/targeting#sponsored-brands

The feature has now been launched, but there is no clear documentation of how it is being reported.
