I activated the privacy policy option for the pre-chat form. This worked great.
But according to GDPR the user has also be informed and must accept about his privacy also when submitting the contact form, which is shown when no operator is available for chat.
So can you also add this link in this template in the next release? This would be great.
BTW: I also tried to modify the template by myself, but found out that these template are not simple html/phtml templates and have to be somehow compile. I never used "Gulp" before - maybe you can write a short tutorial about how to edit the Mibew template? The file mentioned in your documention about theming ("src/gulpfile.js") can not be found in the current release of Mibew.
