Allow FE-previewing hidden records

[peerlight]

currently the preview of events from BE editing form ("view" button above) only works for hidden = 0

TS is configured with

TCEMAIN.preview {
    tx_seminars_seminars {
        previewPageId = 1234
        useCacheHash = 1
        useDefaultLanguageRecord = 0
        fieldToParameterMap {
            uid = tx_seminars_pi1[showUid]
        }
        additionalGetParameters {
        }
    }
}

PHP 7.2 TYPO3 10.4.30 seminars 4.1.5

frontend just shows "Eine Veranstaltung mit dieser Nummer existiert nicht. Wenn Sie diese Fehlermeldung durch einen Link auf unserer Seite bekommen haben, benachrichtigen Sie bitte den Webmaster. Vielen Dank!" when event record has hidden = 1

TCEMAIN.preview works with news extension. maybe somehting is missing ...
