Comment 17 for bug 1972820

So, this answer is really interesting and not well documented yet.

With my LO version 7.5, when you create a new LO Base file and choose a direct connection to MySQL/MariaDB, the next dialog box offer "Using MariaDB C Connector" : so already, we understand it's more for MariaDB.
But it's not clearly written anywhere ! Even, in the webpage you report https://books.libreoffice.org/en/BG73/BG7302-CreatingADatabase.html#toc9 the direct connection to MySQL looks possible !
I will update the french documentation of Ubuntu about this issue. The Libreoffice documentation should be updated as well (by a good english writer !).
Thanks
