Are there any modules that can be used in Demobuilder to help with GDPR privacy? A scheduler, for example, that erases the sensitive information after a certain period, or a button to press which erases the information.
The erase procedure works for demoinstances just like it could be performed for any production Sugar according to documentation
Have you experienced any issues while following documentation instructions?
In addition to Dmytro's suggestion, I believe the Data Privacy module is hidden in your Instance. So can you go to admin --> Display Modules and Subpanels and drag that module from Hidden section to Available section. Once it appears you can start using that module.
