Yes! Thank you for sharing this information. The authors of the two papers that have led to this recent news story do not address the question of how black holes, which are made of matter that constitutes a small fraction of 4.6% of all the energy in the universe, are responsible for dark energy, when dark energy comprises 70%~ of all the energy in the universe.

Dr. Becky Smethurst on this issue.
An interview with one of the lead authors is available here.
They claim that the reason we see a smooth distribution of dark energy throughout spacetime, despite the supposed source (black holes) obviously not being smoothly distributed throughout spacetime, is because of relativistic effects. Intuitively, one would expect the areas near black holes to be expanding faster than areas far away from black holes, if the cause of expansion was the black holes themselves.
Seems unlikely to me. I am hoping that Dr. Matt O'Dowd of PBS SpaceTime also addresses the topic.
