I have not finished the audio file, but the first part of it outlines this group's plan. Their people, or "patriots", were forcibly entering the capitol with the intention of placing Pence, Pelosi, and the generic "Them" under citizens arrest using the authority of "We The People". It is not clear to me if they are referring to the preamble of the US Constitution or some organization or other law. At least one of the speakers was cautioning the Patriots to refrain from using violence, if possible, but the emphasis is to stop the certification of the vote at all costs.
During the attack, there are several voices. Some are clearly at home providing updates from what they see on TV, social media, and right-wing information sources. Some sound like they are at or in the capitol providing on-the-ground information. Through the part I listened to, getting ahold of Pence was the primary goal. It was also clear that his well being wasn't a major concern.
ETA: Oh, and I should mention that their perspective and sources were seriously skewed. At one point, some declares that there are millions of people storming the Capitol. Another person sets the number at 4 million. They were also relaying right-wing reports of Antifa in the crowd breaking windows.
