phpmyadmin 6.0.1 don't work with myaql 8.0?

[Epoche-Napoleon]

Hello,

can it be that the EXT:phpmyadmin 6.0.1 is not yet compatible with TYPO3 11 LTS and mysql 8.0?
I get the following error after database update in BE:

PHP Warning: Undefined array key "extConf" in /html/epochenapoleon/public/typo3conf/ext/phpmyadmin/ext_tables.php line 22

Unfortunately, I can't perform a DB update in the install tool either. The instance is a composer based installation.
Do you guys have any idea what I need to do here?

The check for broken extensions gives the error-message:
Loading ext_tables.php of extension "phpmyadmin" failed
