phpMyAdmin Button not showing in BE on TYPO3 10.4

[cbaur]

Hello everybody,

I've got a client project with an old TYPO3 10.4 instance which should be migrated to the latest version. Unfortunately the mysqldump command is not avalaible on the SSH CLI, so my approach was to install the phpmyadmin extension via composer which seemed to work fine. The extension shows up in the Extension Manager and can also be configured in the Settings Module but there is now button for phpmyadmin anywhere in the module list.

I did check the following possible issues:

• extension is activated
• my IP is in the configured list of allowed IPs
• my user account is a system maintainer

Any ideas why I cannot access phpmyadmin via the menu? Maybe someone could tell me the URI of the iframe to be loaded so I don't even need that button.
