Autoclicker for XBox One?

Is there such a thing?

No.

Are there other possibilities?

No, you'd have to program something like that yourself.

My IT understanding is not sufficient for this.

Unfortunately not. Only on the PC.

You will find a mouse that has such a function.

Or build something for yourself that automatically clicks on your mouse.

Ne Soory, don't know anything here. But it is very difficult to do something like this for XBOX, because the software is relatively well protected and you can't get in via a computer or cf.
