Hi Nicolas and Adamu,
the message "SAGA version 7.8.2 is not officially supported - algorithms 
may encounter issues." is only a warning message, not an error message.
The meaning of the message is about the fact that QGIS developers only 
take (actually, took) care of some files (the "description" files), 
needed by the SAGA processing provider, that are suited for the version 
2.3 of SAGA. Since the SAGA version installed by the OSGeo4W installer 
on Windows is SAGA 7.8 and the "description" files are programmatically 
created by SAGA itself and they are not maintained by the QGIS 
developers for such SAGA version, then the warning message appears.

It only means that the SAGA processing algorithms should work, but some 
of them may be not work... The warning could be disabled, if annoying, 
just commenting out some lines in Python. For more details, please see 
https://github.com/qgis/QGIS/issues/46837.

So, actually there is an issue only if one particular SAGA algorithm 
doesn't work as expected and throws real error messages.

Best regards.
