Quote from the fifth paragraph in https://www.universetoday.com/155146/asteroid-ryugu-might-actually-be-a-dead-comet/

“A lot of Hyabusa 2’s evidence supported the idea that Ryugu is an asteroid, which astronomers assumed was the case since its discovery in 1999. But one thing stood out among the evidence that didn’t fit with the asteroid definition: Ryugu has a high concentration of organic matter.”

“The organic molecules detected include CO, CO2, methanol, carbonyl sulphide, formaldehyde, formic acid, methane, and cyanate.”

“Comets like Ryugu have the same organics as carbonaceous chondrite asteroids, but they’re concentrated on the surface. “The local concentration may account for the extremely high organic content inferred from albedo,” the paper states.”

Asteroid Ryugu originated from Mars, no matter you call it an asteroid or a comet. Evidence for my claim: https://www.flickr.com/photos/fossil_lin/albums/72157718191849106
