There was an attempt at debunking the lab leak theory early on with a nature article saying we do not believe any type of laboratory-based scenario is plausible. Then there was a rejected DARPA research proposal detailing exactly how the laboratory-based scenario is possible.
Lab origin has not been proven but there is no natural zoonotic path to Wuhan. Lab encouraged gain of function with in species reproduction seems most likely.

China continues to withhold data from the WHO regarding the outbreak in Wuhan. That in itself is not proof, but now, seven years into the pandemic, I personally find it suspicious. The other indicators supporting the lab-origin theory are well known. Aside from the incompetence of the Trump I administration, it seems that some intelligence agencies still subscribe to this theory.
