Pangolins were proposed very early in the pandemic, but have been pretty much abandoned. It eventually came to light that all the pangolin papers were based on the same one batch of smuggled pangolins. This makes it more likely that those pangolins were infected by a smuggler (in the same way that housecats or mink have been infected by people), and not the other way around:

All of these are speculative, since no infected animal (except animals probably infected by humans) has been found. The absence of infected animals isn't proof of unnatural origin, but it's different from SARS-1 and MERS, despite a much greater effort to search.
And as you say the path for this particular coronavirus is still debated:
