TL;DR
"Nakajima et al. presented James Webb Space Telescope observations of the z = 6.6 Population III (Pop III) candidate LAP1-B, which is gravitationally lensed by galaxy cluster MACS J0416. We argue that this is the first object to agree with three key theoretical predictions for Pop III stars." From the paper abstract.
"Pop III stars are thought to be composed entirely of helium and hydrogen with trace amounts of lithium, the ingredients left over after the Big Bang. They formed early on, around 200 million years after the universe began. These stars are extremely rare because they died out long ago, although scientists have hoped that the faint light from these distant, ancient objects would be detectable.

Previous Population III candidates have been ruled out because they didn't meet the three main predictions about their formation and properties."

This paper is claiming the main criteria have been met.
