Unsubscribe Function

Hi,

i have installed the Plugin and during testing i was wondering about 2 missing functions / options.

1. Where can i delete the data about subscribers:
If a user types “Stop” in the chat, he/she can unsubscribe from the chat. This should remove the data from my website, shown in Backend under:
/wp-admin/admin.php?page=wp-chatbot-contact

most convinient way would be automatic deletion, but if not possible, there should be at least the option to delete it manually?

2. Where can i change the language of the unsubscribe dialoges?
While a user types “Stop” the language of the messages change to english allthough i have selected “German” in the settings.

Message 1:
“Do you want to unsubscribe? Click [CONFIRM] to verify.”

Message 2:
“Thank you. Your request has been processed.”

Under settings is stated :
“Facebook SDK is not supporting all languages.., please don’t consider it, as an error”

I don’t think that Facebook has no Translations for “German”. Could you please check if this is a Bug?

thank you in advance
