does subRowsKey prop exist in v7?

[dnquang1996vn]

I want to make an expanded table like this example on the official page https://react-table.tanstack.com/docs/examples/expanding. But I want to change subRow key of a row from 'subRows' to 'children' because this is the result which the API return
From #98 (comment), I know it is possible to do with subRowsKey prop in v6.
However, I cannot find this prop in version 7. Can someone help me?
