Forms Double Opt In not working

TYPO3 Questions Extensions
1

Hello,
I want to use the forms extension with the double-opt-in extension.
I have installed these extensions with composer and added double-opt-in-template.

I created a form and added double-opt-in as the first finisher.
The double-opt-in-plugin is inserted in a typo3-folder.

Submitting the firm results in an Email to the sender. But this mail neither contains a link for validation nor for a deletion of the request.
The translation of my German mail is:
Hello Bernd,

double-opt-in-2
double-opt-in-2396×473 8 KB

What did I miss in my configuration? The documentation is not very detailed.
Regards Bernd

Hi @bernds!

Please post a link to the extension you mean on extensions.typo3.org or the extension key.

You may also want to tag the extension developer in your post or reach out to them directly.

Please double check that you included the site set (TYPO3 13) or the TypoScript (TYPO3 12) and that you properly configured the page id containing the plugin for double opt in.
