How can I obtain invoice link to share via text message or social media message?

I have the steps where you can get the link, projectshopvilla.

When you're done creating the invoice, you can open it again and follow the steps below to get the link: 

1. Go to Sales > Customers.
2. Select the customer's name on the list. 
3. Find and open the invoice. 
4. In the Invoice page, click the drop-down arrow next to the Save and close. 
5. Choose Save and share link.
6. Click the Copy link button in the Send your customer a link to their invoice window. Then paste and send it via text or any other messaging platform.

Having the same struggle.  I make sales through social media channels.  Today I did get a new prompt when going to invoicing saying it is now easier to share link directly with quickbooks and copy for social media.  However your screenshot doesn't match what I'm seeing.  I just get the error: "Please add the customer's email address to share this invoices's link."  No other option to copy link.
