Hi Caio,
I would try to use Split operation to extract necessary information.
To extract firstname it would be pretty easy as you can use space as delimiter and take first item from the array.
With rest it might be a mor tricky as I suspect alnumber of last names can be different for different users. If you are able to defina what is expected maximal number of lastnames you can try First Valid eg. 5 times to check all possible lastnames.
