....I read that is only supported in last core version 25 and for moments I can't try it because I only have 23 and is a testing node that I don't control.
Have you tested it with success on what core version?
Yes it works, I just did a quick(ish) test on a 25 node following what nc50lc posted.
This is going to be a bit more snarky then I want it to really come out as, but why are you testing / running on an older node that you don't control?
23 is at maintenance end and will be full EOL in 7 weeks:
https://bitcoincore.org/en/lifecycle/If you are going to be using this to provide a service you should be on a newer version of core.
As I said, it looks more snarky on a screen then I am trying to be, but something you should be thinking about.
