MariaDB - REGEXP_SUBSTR Auto-Completes, but "No Documentation Found"

I am using MariaDB 10.6.19, which supports the various REGEXP_* functions. When writing a query in the Console, I get the auto-complete for these functions, showing their parameters, etc, but once the function is auto-completed, it shows up with a grey underline and there is “No Documentation Found” for it. My expectation is that I should be able to see the documentation. For example, functions like SUM or COUNT have complete documentation when I use the Ctrl+Q shortcut key.

I couldn't find any setting to tell DataGrip what version of MariaDB I'm using. Is there some additional configuration I need to do to get the documentation for these functions?
