dotdigital Chat / M2 Support

[lianastaskevica]

Description:
The Chat widget is available on all pages of your store, although there is a delay of a few seconds before it appears on each page to give the customer the opportunity to view the entire page. The Chat widget can be hidden from view as needed, and restored by clicking the button in the lower-right corner.
