Specifically, when you select Invoice Creation Enabled and create an Invoice along with your Payment link that doesn't auto advance. Is this the same Invoice object as what is used by Invoice API., i.e. I can programmatically update the lineItems of the Invoice at a later date to reduce the overall cost or increase it?

Additionally, are Invoices shared with Connect Accounts so that they can make the edits on their separate connect account portals or do I have to handle these edits programmatically.

Similarly do I have to change status of the invoice or can the Connect Account Change the status of the Invoice on their portal?

I'm trying to see if PaymentLinks would work for our variable pricing service marketplace, users would be given an average price and potentially charged that price and sellers can update the price later to accurately reflect costs. I would like to use PaymentLinks instead of a custom flow.
