Questions about migrating airtable data to baserow

hello, I’m migrating from airtable to baserow.

I’m trying to use the corresponding blocks but the way I get the data is different and I can’t use the same logic.

can anybody help me ?

here i have an example after getting all rows.
the structure is the same in both banks.

this is how I do the distribution with airtable, I would like to know how I could do it with baserow.
