Idiomatic way to add a row in another doc in Nov 2023?

[Ed_Liveikis]

Requirements

1. The triggering document needs to send data to the target document, e.g. to create a new row in that document with incoming data.
2. The action in the other doc should be relatively immediate, so using a cross-doc table to trigger something in the other doc is too slow.
3. Ideally very straightforward, using standard formulas and actions.

In the past what I’ve done is:

1. Create a form in the target document to trigger the action in.
2. Create a button in the triggering document and then open a window to the target document’s form, feeding input data into the form’s URL parameters.

Example formula:

OpenWindow(
  format(
    "https://coda.io/form/formName?param1={1}",
    thisRow.RowId,
  )
)

Are there better alternatives today? Perhaps by using the new document embeds?

Thank you!
