Let's take this a point at a time:
"The first is Hunter Biden was put on the Burisma board."
Well that's true.
"Second, he was put on that board with no qualifications."
That's false. He previously served on the board of Amtrak, appointed by President George W. Bush.

"Third, Burisma, asked him, can you weigh in with DC to relieve the pressure we’re under from the prosecution, from the prosecutor here in Ukraine?"
That's false. The prosecutor in Ukraine was FAILING to investigate corruption, that's why the IMF wanted him removed. That's why the Ukranian ambassador from the US wanted him removed. That's why 100 members of Ukranian parliament wanted him removed.

"And fourth, Joe Biden did just that. He leveraged our tax money to get the prosecutor fired."
That's true, after multiple levels of both the US and Ukranian governments asked for it to happen. Biden got it done.
"And that fourth fact is, is validation of what the confidential human source said in the 1023 form. So that is what is central to this case."
No, it isn't. The 1023 form is a statement of "someone told us x", it has no validation.
