Why can’t the jury ask questions during a trial?

So the point in the trial is to determine whether it can be established beyond some standard (usually “beyond a reasonable doubt”) that the defendant is guilty of the crime they’re accused of by convincing a randomly chosen jury of peers.

Outside of the courtroom it’s pretty standard that if you’re trying to convince someone of something then you talk to them and give them an opportunity to ask questions if there’s part of your argument they don’t understand. They know what it would take to convince them so they’re best-placed to ask questions in order to reach a resolution.

So why isn’t this a thing in court? If the defendant and prosecutor are both trying to convince a jury then why can’t they speak directly with the jury and ask/answer their questions?
