Besides the proof of module results which I have seen in one or two other application forms, I have not seen other firms ask for these documents at this stage either. However, I do not expect the fact that you do not have an official university transcript to be a big issue. Recruiters are aware that some universities only make transcripts available upon graduation and sometimes charge fees for earlier issues.
In my case, although firms preferred receiving transcripts, they were happy to accept other official documents evidencing my grades. These were either module results notification emails or screenshots of my modules results breakdown on my university's student portal webpage. I think it is likely
Dentons would accept the same type of evidence in your case, but if you are worried about this it cannot hurt to send the graduate recruitment team an email explaining your situation and asking for clarification.
