I've never worked in virus research, but my understanding is that any researcher would be keeping meticulous records of every virus they're studying, as well as detailed information about genetic differences with any variants they have produced. So if the Chinese govt simply seized access to all research projects at the lab at Wuhan they would have been able to compare all viruses within the lab with SARS-Cov-2 within a matter of weeks and have an extremely confident Yes or No as to whether it came from their lab.
I'd love to be refuted on the above by someone with actual viral research experience because the alternative conclusion is that the Chinese govt has known the true origin of SARS-Cov-2 since early 2020 and simply won't tell anyone.
