Hello @IbarraJavier,

welcome to the o2 Community!

You already got the right answer from Sächsin. However, I will translate it into English again here:

@Sächsin’s answer is of course the right one here. I only post my translated message as the best answer because it is an English question and therefore the English answer comes directly first.
