The medium post, Is Azov Neo-Nazi? An Expert In Far-Right Radicalism Answers The Common Questions, does a good job of addressing the disinformation about the Azov Regiment.
This article from NBC acknowledges the history of Nazis in Ukraine while making it clear that this history does not justify an invasion of Ukraine. The United States also has a history of Nazis and that of course does not justify military action against the US.
This article from France 24 reported how Azov Regiment has been de-ideologised.
A starting point for learning about this topic is the Azov Brigade wiki page. Specifically, the references section at the bottom of the page has numerous links to news sources.

The people who formed the Azov Brigade and are responsible for its history of Nazi ideology and symbols are now part of a far-right political party called the National Corps. Andriy Biletsky and the people who make up the National Corps political party are neo-Nazis who deserve scrutiny. However they have no political power and do not represent a majority of Ukrainians. Their existence does not justify the invasion of Ukraine by Russia.
The content linked in the references section is where to get information. The wiki page provides a useful summary, but should not be the primary source of information.
