TYPO3 10 Use shortcut in own extension - typo3

Question

I want to display my own extension in TYPO3's CE Shortcut.
The button for my extension is displayed under the listview as button. And I can select an entry and it's saved. But I can't access the selected id in the frontend.
What I tried so far:
I added in /Configuration/TCA/Overrides/tt_content.php the Method addToInsertRecords. So the button to select an entry is shown up in the backend.
defined('TYPO3_MODE') or die();
call_user_func(function () {
\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addToInsertRecords('tx_eislist_domain_model_eis');
});
To show in Frontend the Typoscript is:
tt_content.shortcut.20.tables := addToList(tx_eislist_domain_model_eis)
tt_content.shortcut.20.conf.tx_eislist_domain_model_eis = USER
tt_content.shortcut.20.conf.tx_eislist_domain_model_eis {
userFunc = TYPO3\CMS\Extbase\Core\Bootstrap->run
extensionName = EisList
pluginName = Eis
vendorName = Emma
controller = Eisbar
action = show
switchableControllerActions {
Eisbar {
1 = show
}
}
settings =< plugin.tx_eislist_eis.settings
settings {
insertRecord = 1
useStdWrap = singleRecords
displayMode = single
singleRecords.field = uid
}
}
tt_content.shortcut.variables.shortcuts.tables := addToList(tx_eislist_domain_model_eis)
tt_content.shortcut.variables.shortcuts.conf.tx_eislist_domain_model_eis < tt_content.shortcut.20.conf.tx_eislist_domain_model_eis
In PHP with
$this->settings['singleRecords']
I can access the variable from TypoScript. But I get the string "field" => "uid". Instead of the selected value ID.

I think you need to inject configurationManager to get stdWrap functionality from / in setup typoscript file. Just use a configurationManager variable and an injectFunction in your controller which contains the show action:
/**
* #var \TYPO3\CMS\Extbase\Configuration\ConfigurationManagerInterface
*/
protected $configurationManager;
/**
* Injects the Configuration Manager and is initializing the framework settings
*
* #param \TYPO3\CMS\Extbase\Configuration\ConfigurationManagerInterface $configurationManager Instance of the
* Configuration Manager
*/
public function injectConfigurationManager(
\TYPO3\CMS\Extbase\Configuration\ConfigurationManagerInterface $configurationManager
) {
$this->configurationManager = $configurationManager;
$originalSettings = $this->configurationManager->getConfiguration(
\TYPO3\CMS\Extbase\Configuration\ConfigurationManagerInterface::CONFIGURATION_TYPE_SETTINGS
);
// Use stdWrap for given defined settings
if (isset($originalSettings['useStdWrap']) && !empty($originalSettings['useStdWrap'])) {
$typoScriptService = GeneralUtility::makeInstance(TypoScriptService::class);
$typoScriptArray = $typoScriptService->convertPlainArrayToTypoScriptArray($originalSettings);
$stdWrapProperties = GeneralUtility::trimExplode(',', $originalSettings['useStdWrap'], true);
foreach ($stdWrapProperties as $key) {
if (is_array($typoScriptArray[$key . '.'])) {
$originalSettings[$key] = $this->configurationManager->getContentObject()->stdWrap(
$typoScriptArray[$key],
$typoScriptArray[$key . '.']
);
}
}
}
$this->settings = $originalSettings;
}
