Subaccounts & Multi-User Accounts

Hi,
I want to buy this plugin: https://woocommerce.com/it-it/products/subaccounts-multi-user-accounts/
I have 2 question:
1- Can I have a demo link? I would like to do some tests in the admin, because in my site I have some custom plugin and I want to see if your plugin can work well with my site.
2- Can each account log in with its credentials and have its own shipping address that others do not see?

Waiting,
thanks.
