There's no proof of "gain of function" experiments at all or specifically linked to Sars-Cov-2. It is heavily unlikely that such an experiment would switch a virus from un-pandemic-able to pandemic-able. The mechanisms to do that are entirely theoretical. So it's not clear at all that gain of function would have been able to create a Virus like Sars-Cov-2 out of a hypothetical bat virus. And there is no evidence any such research has been going on. Nor is there any evidence the virus has passed through the Wuhan lab in question at all.
