Why doesn't the Code Connection for Minecraft app work?

I have Windows 10 so it should work for me

Maybe the wrong version of Minecraft

Did you start Minecraft?

No. I have the latest release version.

Yes

Doesn't have to be - / connect 192.168.2.111:19131

That's how I read it. This entry should be made in Minecraft

I did that, but then "connection to server failed"

You must have Minecraft Education Edition for it to work.

Windows 10 Edition works too.

I installed everything to be able to do it. The Education Edition is Win10 based, but you need an account because it is a system in a class association (school, teacher, etc.)
It is a programming environment designed to teach lessons with Minecraft.
For me, the execution fails because my account does not have the authorization (teacher).

A demo version can run.

You don't need authorization for Windows 10 Edition

I would be very happy if you let me know if there's a solution.
Another question, which Win10 - home or pro or?

Windows 10 pro

Could it be because I have the java version of Minecraft?

Yes, the program and the / connect command only work for the Windows 10 edition of Minecraft
