That is a joke of a “review”, and should never have been published.

Consider that it doesn’t mention the only randomized controlled trial of masks and Covid ever performed (it showed no significant protective effect), which was conducted during the period the “review” was being compiled:

There’s simply no excuse. the authors cherry-pick and misinterpret top-line data to craft a narrative. It’s not a review, it’s an editorial.

You should note well that the study you point out made no assessment of whether mask wearing reduced the risk of spread from the mask wearer to others, which is a key point of the utility of mask-wearing during this pandemic.

It is very deceptive for you to claim that this is the only trial of “masks and COVID” when you omit that nuance.

I'm not familiar with that study, but I think it's important to note that the PNAS article was submitted mid-2020, so it's hard to understand your criticism here.
