In this article, I read that astronomers used Gravitational Lensing to measure the Hubble Value:
I then added code to my simulator of Steady Rate expansion to track observed light that is deflected by an object to an observer. It turns out that multiple images from an object emitted at the same moment in time all yield the same Hubble Constant value to any observer. In other words, yet another hit for this model. This model would predict what these scientist saw and offer an alternative interpretation of the data.
I added the approach I used to code of Gravitational Lensing into my simulator and the data that came out of it. You can see on my website, search for "Gravitational Lensing" There are two entries. The first explores lensing in a clean expansion environment. The second, with the observer out of sync in the expansion motion.
Both would offer what these scientist are reporting. However, they do not give much detail as to the nature of the data or how they analyzed it.

Here is the main thrust of what I added to my website concerning Gravitational Lensing:
