draftOrderUpdate lineItems

I am looking to add a Line Item to Draft Orders via Shopify Flow and an Admin API request. I currently have the following issues:

  1. It appears that I need to include the existing Line Items in the input and I am not sure how to do so.
  2. I am attempting to use priceOverride to track this Line Item as a product with custom pricing, and it does not seem to be available in this version.

Any guidance would be much appreciated. Thank you!

Managed to handle the previous line items with a for loop. Still looking for the best way within Admin requests in Flow to set a custom price. Thank you!

Am I correct in seeing that an order can have multiple shippingLines but draftOrders only 1? This would also make sense as a shipping line, but we really need to have this at the draft stage so as to include it on confirmations.

I was able to integrate what was needed into a single shipping line.
