Shopify Insert Data

How can we insert the customer address into a slack message?
What about all the products being order?

I used New Order line_items 0 name
New Order line_items 0 sku

but they only show 1 product. If the customer orders multiple products it doesn’t display.

New Order order_status_url also links to the order thank you page.
How can we link to the order page INSIDE the Shopify panel?
