TYPO3 (v13) fluid template onClick atrribute not possible

Is there a way to write this in the fluid template?

<a onclick="history.back()">Back</a>

I have tried these options and they do not work:

<a onclick="history.back()">Back</a>
<f:format.raw><a onclick="history.back()">Back</a></f:format.raw>
<f:link.typolink parameter="1" additionalAttributes="{onclick: 'history.back()'}">Back</f:link.typolink>

All versions only result in the word “Back” or a link without an "onclick"

The problems are caused by the HTMLSanitizer.

Some information can be found here https://punkt.de/de/blog/2021/htmlsanitizer-in-typo3.html (german).

in my case, i have created the following sanitizer

    use TYPO3\CMS\Core\Html\DefaultSanitizerBuilder;
    use TYPO3\HtmlSanitizer\Behavior;
    use TYPO3\HtmlSanitizer\Behavior\Attr;
    use TYPO3\HtmlSanitizer\Behavior\Tag;
     
    class HjuHtmlSanitizer extends DefaultSanitizerBuilder
    {
        public function createBehavior(): Behavior
        {
    
            
            $behaviour = parent::createBehavior()
                ->withName('hju-custom-a')
                ->withTags(
                    (new Behavior\Tag('a', Behavior\Tag::ALLOW_CHILDREN))
                    ->addAttrs(
                        (new Behavior\Attr('href'))->addValues(
                            //to filter values 
                            //new Behavior\RegExpAttrValue('#^https?://#')
                        ),
                        (new Behavior\Attr('onclick'))->addValues(),
                         (new Behavior\Attr('target'))->addValues(),
                        ...$this->globalAttrs
                    ),
                    (new Behavior\Tag('span', Behavior\Tag::ALLOW_CHILDREN))
                    ->addAttrs(
                        (new Behavior\Attr('onclick'))->addValues(),
                        ...$this->globalAttrs
                    )
                );
                
            
            return $behaviour;
                
        }
    }
