typo3 11 extbase QueryResultPaginator doesn't work. Only the first page will be shown, cklick on a higher page leads to the searchbox again - typo3-11.x

Question

I have a search input box to take a string in the frontend with suchfensterAction. The result seems to be correct. But when I click to page 2 or higher I always get the suchfensterAction and never the higher paginated page.
(static function() {
\TYPO3\CMS\Extbase\Utility\ExtensionUtility::configurePlugin(
'Myext', 'Myext',
[...\Controller\MyextController::class => 'suchfenster, list,show, new, .....
To show the result in the frontend with pagination i have used following controller code:
...
public function suchfensterAction()
{
return $this->htmlResponse();
}
public function listAction(int $currentPage = 1): \Psr\Http\Message\ResponseInterface
{
$args=$this->request->getArguments();
$gefunden=$this->absolventenRepository->search($this->request->getArguments());
$itemsPerPage = 15;
$arrayPaginator = new \TYPO3\CMS\Extbase\Pagination\QueryResultPaginator($gefunden,
$currentPage, $itemsPerPage);
$pagination = new SimplePagination($arrayPaginator);
$this->view->assignMultiple(
[
'paginator' => $arrayPaginator,
'pagination' => $pagination,
'pages' => range(1, $pagination->getLastPageNumber()),
]
);
return $this->htmlResponse();
}
...
and the templates suchfenster.html
<f:form action ="list" >
<f:form.textfield autofocus ="1" name="query" value="{queryvalue}" placeholder = '{text}' />
<f:form.submit value="Suchen"/><br>
</f:form>
...
und list.html
...
<table>
<f:for each="{paginator.paginatedItems}" as="item" iteration="iterator">
<tr><f:render partial="Item.html" arguments="{item:item}" /></tr>
</f:for>
</table>
<f:render partial="Paginator.html" arguments="{pagination: pagination, pages: pages,
paginator: paginator}" />
...
My Paginator.html:
<ul class="pagination pagination-block">
<f:if condition="{pagination.previousPageNumber} &&
{pagination.previousPageNumber} >= {pagination.firstPageNumber}">
<f:then>
<li class="waves-effect">
<a href="{f:uri.action(action:actionName, arguments:{currentPage: 1})}" title="{f:translate(key:'pagination.first')}">
<i class="material-icons">first_page</i>
</a>
</li>
<li class="waves-effect">
<a href="{f:uri.action(action:actionName, arguments:{currentPage: pagination.previousPageNumber})}" title="{f:translate(key:'pagination.previous')}">
<i class="material-icons">chevron_left</i>
</a>
</li>
</f:then>
<f:else>
<li class="disabled"><i class="material-icons">first_page</i></li>
<li class="disabled"><i class="material-icons">chevron_left</i></li>
</f:else>
</f:if>
<f:for each="{pages}" as="page">
<li class="{f:if(condition: '{page} == {paginator.currentPageNumber}', then:'active', else:'waves-effect')}">
{page}
</li>
</f:for>
<f:if condition="{pagination.nextPageNumber} && {pagination.nextPageNumber} <= {pagination.lastPageNumber}">
<f:then>
<li class="waves-effect">
<a href="{f:uri.action(action:actionName, arguments:{currentPage: pagination.nextPageNumber})}" title="{f:translate(key:'pagination.next')}">
<i class="material-icons">chevron_right</i>
</a>
</li>
<li class="waves-effect">
<a href="{f:uri.action(action:actionName, arguments:{currentPage: pagination.lastPageNumber})}" title="{f:translate(key:'pagination.last')}">
<i class="material-icons">last_page</i>
</a>
</li>
</f:then>
<f:else>
<li class="disabled"><i class="material-icons">chevron_right</i></li>
<li class="disabled"><i class="material-icons">last_page</i></li>
</f:else>
</f:if>
</ul>
Where I have to control the argument 'currentPage'? bzw. where I have to increment 'currentPage'?
