Grundig Fire TV remote control change buttons?

I have the remote control shown below with the buttons Prime Video, Netflix, DAZN and TVnow.

Now I use e.g. Not DAZN, but often YouTube: Is there somewhere in the settings the option to change the target of this button?

So that when I press the DAZN button, YouTube opens?

Did not know that that would work with a TV FB

But just take a look at the operating instructions, if you can, it will certainly be there

No, the instruction manual says nothing about the remote control, but it also says nothing about developer options or the X-Ray system… Many things are patched, but the instruction manual is rarely updated.

So… This is a standard FB and it would be new to me that you could change their key assignments.

I have never heard / read / seen…

Sorry, Grundig also says on it, they are limited to a 08/15 operating manual and then it says "can handle it or leave it"

Do they now have no help built into the TV or are they still lagging behind?

In itself, it's an Alexa voice remote with more buttons. This is actually not difficult to program and is also coupled via Bluetooth and not IR.

The internal help is only the manual: If you ask something that is not in it: "Unfortunately I couldn't find anything, but maybe something interests you that never interested you."

I thought that maybe you could couple the FB to the computer and then I could change the key assignment via Powershell / CMD, because as I said it works via Bluetooth and should theoretically have a "system".

Sure… It could be possible, look it up on the internet

Maybe someone has already dealt with it…
