Invite Only Group. Invite on purchase via email?

Hi Stackideas Team

I want to sell access to an Easy Social Group with Hika Shop and your Hika App.
My product would be for e.g. "access to Group ABC”
As of now the Hika Shop App does not allow me to put a buyer of a product automatically in a group.

In Hika Shop when some ones buys a product eg “access to group ABC”

They get a mail from Hika shop confirming the order.

I am wondering is it possible to put some kind of generic you are invited to join group ABC link into this mail?

thanks

Paul
