As of macOS Big Sur, how do you see generator used by Quick Look?

Before macOS Big Sur, qlmanage -p by itself or qlmanage -p -d debugLevel showed which Quick Look generator was used for a given file. Now, no such info appears. The man page for qlmanage also changed from > qlmanage -p [-d debugLevel] [-x] [-c contentTypeUTI [-g generator]] [file ...] to > qlmanage -p [-x] [-c contentTypeUTI [-g generator]] [file ...] **How can I, as of macOS Big Sur, see what Quick Look generator is used for a given file?**
