In the automation of a create row condition, how do I determine the id value of the created row?

I'm trying to be able to sort a formula column that can't be used for sorting.

I saw in a link that the next best thing is to use automation.
The idea is that when a new row is created, copy the value of the formula into a regular text column, and since the column is text, it can be used to sort.

The procedure described in the link is as follows.

1. start creating an automation with 'row create' type
2. query the newly created row to get it.
3. use the update row step to modify the desired column of the row (copy formula value to regular text column)

My question is, in #2 above,
How can I get the row that was just created, the row that corresponds to the condition that triggered the trigger?

When I look at the query rows part in budibase automation, it basically fetches all rows, but I think I need to set a filter condition here to get the rows I want, the ones I just created.

I've specified _id in the matching filter, the method is binding, and the content of the binding is {{ trigger.id }} for the content of the binding.
But when I look at the output, all rows are returned.

I would really appreciate if you could tell me how to get only the rows that were created in the above step.
