Uh, pretty obviously that the President wanted Zelensky to investigate the Bidens, and he was using the military aid as leverage.
@Catchall, look I understand that you have this weird tendency to ignore context and think only an explicit request by Trump to "do this for me and I'll do that" would constitute leveraging his presidential powers to get a favor from a foreign leader, but that's really not the standard.
An explicit request to "do this for me and I'll do that" (quid pro quo) would give the Dem's impeachment effort concrete evidence to support the claim that Trump was threatening to withhold aid if Ukraine doesn't investigate the Bidens. Maybe that's really what happened. Maybe there really is evidence out there somewhere that shows this. However, the phone conversation doesn't say that. Not even close. That's why Adam Schiff made up his own dialog during yesterday's hearing and couldn't point to the call transcript that everyone had in front of them.
Unfortunately, legal investigations do care about concrete evidence and not just innuendo or trying to subjectively read tea leaves. This isn't a "weird tendency," it's the rule of law. The prosecution has a burden of proof and has to show at least a minimal standard of knowledge/purpose/intent. The evidence in the call transcript is circumstantial at best, and it wouldn't hold up in a real investigation.

Zellenskyy was the one who brought up the topic of corruption, even using the phrase "drain the swamp," early in the call. It was a major part of the campaign he ran on. He's the one who volunteered that a new prosecutor who supports his administration will be hired. When Trump entered into the conversation on corruption, it started in relation to the DOJ investigation that involves Ukraine, which the Dems seem to know little about, or seem to be discounting. That's state business and not Trump's personal campaign. That's why Bill Barr was relevant to the conversation.
The Dems don't seem to grasp this. They seem to think the only reason Trump would talk about corruption with Ukraine is to try to "dig up dirt" on Joe Biden. They think Trump is trying to use Barr as a personal lawyer. However, when that DOJ report eventually comes out, it will become abundantly clear why Trump and Zellenskyy were talking about corruption and why Barr was brought into the conversation.
Then Trump raises the question about the Bidens, first asking Zellenskyy to look into the circumstances around which the state prosecutor got fired and whether what Joe Biden did was fair. There's nothing wrong with hearing Zellenskyy's version of the details of what happened. That was Biden acting in an official capacity. It's going to be handled by Bill Barr, if anyone.
Trump then goes further and asks about Hunter Biden. This is where it gets murky for me. Why does Trump care about Hunter Biden unless he wants to use that information make a personal attack on Joe? Yes, there's a pretty clear conflict of interest there, but it was years ago. It would be on the periphery of current corruption investigations. Trump is stretching the topic, but he's shrewd enough to be coy about it.
As it stands, Trump released the financial aid to Ukraine, Zellenskyy said this week that he hasn't investigated corruption, and Zellenskyy also said he didn't feel "pushed" by Trump to do so.
Even if you can read in bad intent on Trump's part, where's the actual infraction? It's like saying Trump wanted Robert Mueller to be fired, but actions weren't taken.
It's a weak case.
