Edit: This isn't true!

There is an option to not ask for the apple id password for TestFlight IAPs when using the purchase function from StoreKit:

try await purchase(product, options: [.simulatesAskToBuyInSandbox(false)])

Or:

try await product.purchase( options: [.simulatesAskToBuyInSandbox(false)])

But it won't even throw up a modal asking the user to buy and instead just successfully completes and buys the product.
I think.

@hannesmnagel @atpfm Whoah, I had no idea about this. Thank you!
