On checking there have been reports on that both the module and the final rocket stage were seen in close proximity in the day or two after the launch, however no mention of them in turn being seen in close proximity/trail of the ISS….
The one or two apps available that allow retrospective calculation of the position of ISS position seem to show that the station was behind Nauka, in fact over north east Africa, at around the time the module achieved orbit but I can’t ATM vouch for the accuracy of those applications….
