Get group_id from DealFields

Hello there!

I have some created Data fields that are grouped. When I call the ‘Get all deal fields’ from the API I can see that these created fields have a ‘group_id’ with an int related. Is there a way to get this group_id from the API?
This image shows the created data fields with the related group:

Here I can see the field with the group_id parameter equals to 43, that on the image above is ‘Detalhes do cadastro’ (group title).

I’ve already checked that the group_id is correct to all the groups that I created inside the Data fields page.

Thanks!
